You can allow or disallow these services on a tunnel interface: all (Overrides any commands that allow or disallow individual services). You use a loopback interface because it is always reachable when the router is operational and when the overlay network is up. However, you can choose to instead use ICMP to perform PMTU discovery: BFD is a data plane protocol and so does not run on vBond, vManage, and vSmart devices. In the Viptela overlay network, you configure network interfaces within individual VPNs. In this example, local traffic is directed to the GRE tunnel using a centralized data policy, which is configured on the vSmart controller. One subinterface binds to the Internet circuit, and the second one binds to the MPLS connection. It is similar to a router ID on a regular router, which is the address used to identify the router from which packets originated. You can optionally associate a color with the tunnel. Each TLOC is uniquely identified by a 3-tuple comprising the system IP address, a color, and an encapsulation. In the action portion of the data policy, you must explicitly configure the policy to service the packets destined for the GRE tunnel. Connect your device to the router using an Ethernet cable to the gig 0/0/1 interface. A second trap is sent (and subsequent traps are sent) if the bandwidth exceeds 85 percent of the value in 85 percent of the 10-second sampling intervals over the next 1-hour period. When you configure a cellular interface on a vEdge router, you can connect the router to the Internet or other WAN simply by plugging in the router's power cable. Commands for configuration of other routers (1841, 2800, 3825…) will be the same. The default hello tolerance is 12 seconds, and it can be a time in the range 12 through 600 seconds (10 minutes). vEdge(config-interface-ge)# no shutdown. After you establish the connection, you can proceed with the basic configuration of Ethernet, Fast Ethernet, or Gigabit Ethernet connections. This allows subprefix routing information to pass across classful network boundaries. vEdge(config-tunnel-interface)# [no] allow-service service. Configure a NAT on the public-network-facing interface on the vEdge router. You can configure either of these routing protocols on your router. Step: 2. ... Security and multi-cloud capability of the Cisco SD-WAN … A vEdge router can act as a DHCP server for the service-side network to which it is connected, and it can also act as a DHCP helper, forwarding requests for IP addresses from devices in the service-side network to a DHCP server that is in a different subnet on the service side of the vEdge router. The clock rate command would only apply if the cable connected to the router was a DCE or data communications equipment. For the CLI to recognize as interface as a loopback interface, its name must start with the full string loopback.). You can also statically assign IP addresses to a host: vEdge(config-dhcp-server)# static-lease mac-address ip ip-address. The preference command controls the preference for directing traffic to a tunnel. If you want the routers at the same site to form BFD tunnels between them, enable the formation of these tunnels: vEdge(config)# system allow-same-site-tunnels. Each individual subinterface can be present only in a single VPN. For GRE interfaces, you can configure only the following additional interface properties: vEdge(config-interface-gre)# clear-dont-fragment vSmart(config-tunnel-interface)# color color To create a VPN-Interface-PPP-Ethernet feature template to enable the PPPoE client on the physical interfaces: Enter a description for the PPPoE-enabled interface. To allow the tunnel to be the circuit of last resort: To minimize the amount of control plane keepalive traffic on the cellular interface, increase the Hello packet interval and tolerance on the tunnel interface: Configure any other desired tunnel interface properties. The system interface is placed in VPN 0, as a loopback interface named system. The loopback interface acts as a placeholder for the static IP address and provides default routing information. To enable the interface, include the no shutdown command. You configure quality of service (QoS) and shaping rate on a PPPoE-enabled physical interface, rather than on the PPP interface. The interface type for management interfaces is mgmt, and the initial address for the interface is 192.168.1.1. Cisco routers can be configure as both DHCP servers and DHCP clients. Enters line configuration mode, and specifies the type of line. Click Create to create the device template. The interface number can be from 1 through 31. To verify that you have properly configured the loopback interface, enter the show interface loopback command as shown in the following example. This way, the ISP can provide the IP information to the client device. To configure multiple PPPoE-enabled interfaces in VPN 0, click the plus sign (+) next to Sub-Templates. You can modify the priority value, setting it to a value from 1 through 254: The VRRP master periodically sends advertisement messages, indicating that it is still operating. The pre-requisites for deployment using the Zero Touch Deployment through USB feature are: If the USB flash drive has multiple.cfg files, the router chooses the one with the highest index number in the USB Flash drive. To specify multiple individual addresses, list them in a single exclude command, separated by a space (for example, exclude 1.1.1.1 2.2.2.2 3.3.3.3). Command descriptions: ip address: Adds an address and subnet mask to the interface. On a vEdge router, you can configure up to seven tunnel interfaces. Here is an example of the same configuring using a GRE-specific static route to direct data traffic from VPN 1 into the GRE tunnels: The show interface command displays the GRE interface in VPN 0: You can also view the GRE tunnel information: When a vEdge router comes up, the Viptela software autodetects the SFPs present in the router and sets the interface speed accordingly. vSmart(config)# vpn 0 Specifies a unique password for the virtual terminal line. Specifies a list of networks on which EIGRP is to be applied, using the IP address of the network of directly connected networks. In the following configuration example, the static route sends out all IP packets with a destination IP address of 192.168.1.0 and a subnet mask of 255.255.255.0 on the Gigabit Ethernet interface to another device with an IP address of 10.10.10.2. One use case is to provide wireless connectivity for branch offices. The group number identifies the virtual router. To enable more than one PPPoE interface on a vEdge router, configure multiple PPP interfaces. vEdge(config-dhcp-server)# offer-time minutes. Most IPv6 configuration and verification commands in the Cisco IOS are very similar to their IPv4 counterparts. NAT, PMTU, and tunnel interfaces. Note GigabitEthernet LAN Interfaces are 0/0 to 0/7 for Cisco C841M-8X ISR and 0/0 to 0/3 for Cisco C841M-4X ISR. Changes in dynamic routes are shared with other routers in the network. ... And you will need to configure your router to send netflow data to your collection engine. On vEdge routers, in VPNs other than 0 and 512, you configure the interfaces that carry data traffic between vEdge routers and sites across the overlay network. The most basic parameter for a Router Interface is the IP address. You can also optionally add seconds to the interval value. For more information, see Configuring Centralized Data Policy. Note: When you activate the configuration on a router with cellular interfaces, the primary interfaces (that is, those interfaces not configured as circuits of last resort) and the circuit of last resort come up. Create a VPN-Interface-PPP feature template to configure PPP parameters for the PPP virtual interface. For a tunnel connection between two controller devices, the tunnel uses the lower hello interval and the higher tolerance interval for the connection between the two devices. The default MTU on a physical interface is 1500 bytes by default, so the subinterface's MTU here can be no larger than 1496 bytes. When you configure a cellular interface on a vEdge router, you can connect the router to the Internet or other WAN simply by plugging in the router's power cable. Static routes provide fixed routing paths through the network. When a vEdge router has two or more tunnels, if the TLOCs all have different preferences and no policy is applied that affects traffic flow, only the TLOC with the highest preference is advertised into OMP. From the Templates title bar, select Device. Enter a description for the template. vEdge(config-interface-ge)# ip address prefix/length If the PPPoE server does not specify a maximum receive unit (MRU), the MTU value for the PPP interface is used as the MRU. If one of the routers is connected to two WAN transports (such as the Internet and an MPLS network), create subinterfaces between the two routers, creating the tunnel on the subinterface. While system startup is in progress and push button is pressed, a timer is started to check the completion of second core initialization. The router you are using for Inter-VLAN routing must be compatible and support Inter-Switch Link (ISL) which is a Cisco Systems proprietary protocol, and IEEE 802.1q frame format for routing on the Fast Ethernet interfaces. You can change the VRRP advertisement time to be a value from 1 through 3600 seconds: By default, VRRP uses of the state of the interface on which it is running to determine which vEdge router is the master virtual router. Specifically, interface traffic is sampled every 10 seconds. On vSmart controllers and vManage NMSs, interface-name can be either ethnumber or loopbacknumber. On a vEdge router, services that you configure on a tunnel interface act as implicit access lists (ACLs). In this command, you specify the physical interface that connects to the WAN or private network circuit. They are manually configured on the router. Launch the browser and enter the device IP address in your browser’s address line. The maximum bandwidth is typically the bandwidth that has been negotiated with the circuit provider. You can, however, reconfigure the service itself, by modifying the service command. Configure an IPv6 Router Interface (1.1.3.3) Configuring an IPv6 interface is similar to configuring an interface for IPv4. In practice, you always configure additional parameters for each interface. If you have configured a primary and a backup GRE tunnel, list the two GRE interfaces (grenumber1 grenumber2) in the service command. vEdge(config-interface-gre)# tunnel-destination ip-address In the Transport & Management VPN section, under VPN 0, from the drop-down list of available templates, select the desired feature template. Router(config)# interface gigabitethernet 0/8. Public IP: 193.188.XX XX. vEdge(config-interface-gre)# tcp-mss-adjust. vEdge-2(config-interface)# ip address prefix/length Note that the configuration commans will be the same for all Cisco routers like Cisco ASR1000, ISR 4000 or any other. Specifies an encrypted password to prevent unauthorized access to the router. For this example, you connect two Cisco routers by using a back-to-back cable or DTC-DTE cable, emulating a service provider connection between the two devices. To display an interface's MTU, use the show interface command. One special use of loopback interfaces is to configure data traffic exchange across private WANs, such as MPLS or metro Ethernet networks. The clock rate will set the speed. Create a device template that incorporates the VPN-Interface-PPP, VPN-Interface-PPP-Ethernet, and VPN feature templates. The tloc-extension command creates the binding between the non-connected router and the WAN or private network. Viptela(config-vpn)# interface interface-name arp ip ip-address mac mac-address. To explicitly configure BFD to perform PMTU discovery, use the bfd color pmtu-discovery configuration command. For a tunnel connection between a vEdge router and any controller device, the tunnel uses the hello interval and tolerance times configured on the router. When you extend the WAN transport VPN, no BFD sessions are established between the two collated vEdge routers. To display information about the configured data traffic interfaces, use the show interface command. The GRE interface has a name in the format grenumber, where number can be from 1 through 255. Here we have an example of a configured trunk port on Cisco 2811 router that is connected to a Layer 2 switch. ​vEdge(config-vpn)# interface interface-name speed (10 | 100). If the physical interface goes down for any reason, all its subinterfaces also go down. When a router has two or more TLOCs, all with the highest equal preference value, traffic distribution is weighted according to the configured weight value. To include additional feature templates in the device template, in the remaining sections, select the feature templates in turn, and from the drop-down list of available templates, select the desired template. In the following example, Router-1 is the VRRP master, because it has a higher priority value than Router 2: The Point-to-Point Protocol over Ethernet (PPPoE) connects multiple users over an Ethernet local area network to a remote site through common customer premises equipment. The vEdge router then automatically begins … Notifications are sent as Netconf notifications, which are sent to the vManage NMS, SNMP traps, and syslog messages. In Releases 16.2.0 through 16.2.9, vEdge routers support only one radio access technology (RAT) type, which is LTE. I’m using a HWIC-3G-GSM WAN card but the configuration will be very similar for most of the cards out there. Step 4. vEdge-1(config-interface)# ip address prefix/length In the VPN-Interface-PPP and VPN-Interface-PPP-Ethernet fields, select the feature templates to use. You use a service-side VPN because it is reachable from the data center. For example: For some protocols, you specify an interface as part of the protocol's configuration. With this configuration, the interface forwards any broadcast BOOTP DHCP requests that it receives from hosts on the service-side network to the DHCP server or servers specified by the configured IP helper address (or addresses) and returns the assigned IP address to the requester. You do this using the mtu command. Step 2. interface gigabitethernet slot/port. Enables password verifiation at the virtual terminal login session. Enters the configuration mode for a Gigabit Ethernet interface on the router. BFD PMTU discovery is enabled by default, and it is recommended that you use it and not disable it. The Viptela software supports DHCP server options that allow you to configure the IP addresses of a default gateway, DNS server, and TFTP server in the service-side network and the network mask of the service-side network: vEdge(config-dhcp-server)# options default-gateway ip-address Ensure that you select templates for all mandatory feature templates and for any desired optional feature templates. In the right pane, select the VPN-Interface-PPP-Ethernet template. You can configure loopback interfaces in any VPN. For the router connected to the WAN or private transport (vEdge-2 in the figure above), configure the interface that connects to the unconnected router, again in VPN 0: vEdge-2(config-vpn-0)# interface geslot/port exit: Switches to the previous mode. In this process, all the interfaces begin the process of establishing control and BFD connections. Configuring the first router. The system IP address can be any IPv4 address except for 0.0.0.0/8, 127.0.0.0/8, and 224.0.0.0/4, and 240.0.0.0/4 and later. Data transmitted out an IPsec tunnel can be received only by an IPsec tunnel, and data sent on a GRE tunnel can be received only by a GRE tunnel. When there are three or more tunnels and two of them have the same preference, traffic flows are distributed evenly between these two tunnels. Specifically, the packets are sent to the configured PVC. When a vEdge router has multiple TLOCs, each TLOC is preferred equally and traffic to each TLOC is weighted equally, resulting in ECMP routing. ​When you configure a tunnel interface on a vEdge router, a number of services are enabled by default on that interface, including DHCP. For vSmart controllers and vManage NMS systems, the initial interface speeds are 1000 Mbps, and the operating speed is negotiated with the device at the remote end of the interface. Because vSmart controllers and vManage NMSs participate only in the overlay network's control plane, the only VPN that you can configure on these devices is VPN 0, and hence all interfaces are present only in this VPN. vEdge(config-dhcp-server)# options interface-mtu mtu To display information about the configured interfaces in the WAN transport VPN, use the show interface command. El objetivo de este artículo es el de explicarte cómo configurar un router Cisco, así como brindarte los comandos básico para su gestión. By default, a vManage application server accepts a maximum of 50 HTTPS connections from users in the overlay network. Create a tunnel interface on the cellular interface: By default, the tunnel interface associated with a cellular interface is not considered to be the circuit of last resort. You con configure Serial, 3G/4G, Ethernet, or Broadband (xDSL) as a secondary WAN depending on the WAN types supported by the router. To advertise the service, include the service command in the service VPN (a VPN other than VPN 0 or VPN 512): vEdge(config-vpn)# service service-name interface grenumber [grenumber2]. For subinterfaces to work, you must configure the physical interface in VPN 0 and activate it with a no shutdown command. You should see verification output similar to the following: In dynamic routing, the network protocol adjusts the path automatically, based on network traffic or topology. On the other hand, the WAN interface (FE4) is a normal Layer3 router port, which means you can assign an IP address directly on the interface (“interface FastEthernet4”). I am trying to configure the WAN connection on a 2811 series router, but am not having any luck. Step 3 vEdge(config-interface-gre)# mtu bytes vEdge(config-interface-ge)# vrrp group-number. This tutorial will show how to configure Cisco 881 Series Router with Cable modem in bridged mode and static IP address. Viptela(config-vpn-number)# interface geslot/port Specifies a list of networks on which RIP is to be applied, using the address of the network of each directly connected network. Because the router vEdge-2 connects to two transports, we create subinterfaces between the vEdge-1 and vEdge-2 routers. Specify the system IP address as an IPv4 address in decimal four-part dotted notation. To configure the IP address directly, enter of the IPv4 address of the interface. Enters the configuration mode for a Gigabit Ethernet interface on the router. The template name cannot contain special characters. The combination of a source address and a destination address defines a single GRE tunnel. If slave routers miss three consecutive VRRP advertisements, they assume that the master is down and elect a new master. If the received or transmitted bandwidth exceeds 85 percent of the configured value in 85 percent of the sampled intervals in a continuous 5-minute period, an SNMP trap is generated. At a minimum, for these interfaces, you must configure an IP address, and you must enable it: Viptela(config)# vpn number Viptela(config-vpn-0)# interface interface-name To direct the data traffic to the GRE tunnel using a centralized data policy is a two-part process: you advertise the service in the service VPN, and then you create a centralized data policy on the vSmart controller to forward matching traffic to that service. The maximum MTU for a PPP interface is 1492 bytes. In vManage NMS, select the Configuration ► Templates screen. You can modify these values: vEdge(config-dhcp-server)# max-leases number A valid configuration file can be created by saving the running configuration of a router to flash, USB flash, or to a TFTP Server. In below ACL, we allow all IP in the LAN can access to the internet. Sets the IP address and subnet mask for the loopback interface. If you explicitly configure ACLs on a tunnel interface, with the policy access-list command, the handling of packets matching both implicit and explict ACLs depends on the exact configuration. The Virtual Router Redundancy Protocol (VRRP) provides redundant gateway service for switches and other IP end stations. vEdge-1(config-tunnel-interface)# color color. Step3: Configure IP addresses for Router Interfaces. To delete the GRE interface, you must first delete the service. Small business with a single router (i.e Cisco 1811 ISR), has two ISPs, and would like to use one ISP as the main provider, and the second ISP as a backup in case the first one fails. After the first trap is generated, sampling continues at the same frequency, but notifications are rate-limited to once per hour. Specifies the static route for the IP packets. Step 8. When the router transmits or receives traffic, it sends the traffic only to the TLOC with the highest preference. By default, vEdge routers respond to ARP requests only if the destination address of the request is on the local network. Setting up Wide Area Network (WAN) serial connection management for your Cisco device is quite straight-forward. On vEdge-1, we see no BFD sessions to vEdge-2 (system IP address 172.16.255.16): On all Viptela devices, VPN 512 is used, by default, for out-of-band management, and its configuration is part of the factory-default configuration. Assign an IP address to the physical interface: To create a VPN feature template to configure the PPPoE-enabled interface in VPN 0, the transport VPN: To create a device template that incorporates the VPN-Interface-PPP, VPN-Interface-PPP-Ethernet, and VPN feature templates: To use the CLI to configure the PPPoE on vEdge routers: Here is an example of a PPPoE configuration: To view existing PPP interfaces, use the show ppp interface command. Sets the IP address and subnet mask for the specified GE interface. Because you are using a subinterface, the interface's MTU must be at least 4 bytes less than the physical MTU. vEdge-2(config-interface)# no shutdown To verify that you have properly configured RIP, enter the show ip route command and look for RIP routes signified by “R” as shown in this example. At a high level, for an interface to be operational, you must configure an IP address for the interface and mark it as operational (no shutdown). In the template, configure the following parameters: In the vManage NMS, select the Configuration ► Templates screen. With these default values, if no Hello packet is received within 11 seconds, the tunnel is declared down at 12 seconds. Viptela(config-interface)# no shutdown. On the other hand, the WAN interface (FE4) is a normal Layer3 router port, which means you can assign an IP address directly on the interface (“interface FastEthernet4”). Hence, for packets to be transmitted, either increase the MTU size on the physical interface in VPN 0 (the default MTU is 1500 bytes) or decrease the MTU size on the VRRP interface. A remote vEdge router trying to reach one of these prefixes selects which TLOC to use from the set of TLOCs that have been advertised. A subinterface is a virtual interface created by dividing one physical interface into multiple logical interfaces. vManage NMS displays the feature templates for the device type you selected. To specify a range of addresses, separate them with a hyphen (for example, exclude 1.1.1.1-1.1.1.10). no shutdown: Switches the interface from off to on. To configure a tunnel interface on a vSmart controller or a vManage NMS, you create an interface in VPN 0, assign an IP address, and mark it as a tunnel interface. The EIGRP autonomous system number is 109. The default hello interval is 1 second, and the default tolerance is 12 seconds. By default, routers at one site form BFD tunnels only with routers at remote sites. The trunk interface on the router is divided into subinterfaces with the matching IP addresses for each VLAN subnet. The DHCP service in VPN 0 affects the transport-side network. This choice is made in case one of the controllers has a slower WAN connection. They may differ only in configuration of interfaces, i.e. It will work with any model that has Fast Ethernet WAN interface. vEdge(config-interface)# tunnel-interface In this lesson, you will learn how to configure your Cisco router to use its 3G / UMTS / HSPDA WAN interface. The default hello interval is 1000 milliseconds, and it can be a time in the range 100 through 600000 milliseconds (10 minutes). The first thing that we need to do here to have WAN redundancy with multiple internet connections is to configure dynamic NAT, dynamic network address translation, on Cisco router that connected directly to two ISP. Configure a static route on the non-connected router to the TLOC-extended interface on the router connected to the public network. vSmart(config-tunnel-interface)# [no] allow-service service. To associate a carrier name or private network identifier with a tunnel interface, use the carrier command. For example: To view PPPoE session information, use the show pppoe session command. To configure a GRE tunnel interface to a remote device that is reachable through a transport network, configure the tunnel in VPN 0: vEdge(config)# vpn 0 interface grenumber Each interface can be present only in a single VPN. Let’s take Cisco 881 for example. Step 6. Here, interface ge0/0, which connects to the WAN cloud, is running at 1000 Mbps (1Gbps; it is the 1GE PIM highlighted in the output above), and interface ge0/1, which connects to a device at the local site, has negotiated a speed of 100 Mbps. The following configuration example shows RIP version 2 enabled in IP network 10.0.0.0 and 192.168.1.0. In the right pane, select the VPN template. To allow a vEdge router that is behind a private network to communicate directly over the private WAN with other vEdge routers, you direct data traffic to a loopback interface that is configured as a tunnel interface rather than to an actual physical WAN interface. From Global Configuration Mode you need to enter into Interface Configuration Mode: My-Router(config)# interface … Configuring NAT for multiple Vlans on a Cisco router is a challenge that many inexperienced Cisco network engineers have had to contend with at one stage of their careers or the other. Track the Overlay Management Protocol (OMP) session running on the WAN connection when determining the VRRP master virtual router: Track both the OMP session and a list of remote prefixes. For vBond, vManage, and vSmart devices, you can configure interfaces to use ICMP to perform path MTU (PMTU) discovery. The service name can be FW, IDP, or IDS, or a custom service name netsvc1 through netsvc4. The colors metro-ethernet, mpls, and private1 through private6 are referred to as private colors, because they use private addresses to connect to the remote side vEdge router in a private network. If the configuration files cannot be found, pressing reset button has no effect. For example: To enable LTE connectivity, you configure cellular interfaces on vEdge routers that have a cellular module. … These two alarms are cleared only when all the primary interfaces lose their BFD connections to remote nodes and the circuit of last resort activates itself. Enter up to four IP addresses for DHCP servers in the network. Here I’m going to configure WAN interface of the router with ISP public IP address.. WAN IP : 192.168.1.200 WAN Subnet : 255.255.255.0 GATEWAY : 192.168.1.1 WAN Interface … Hi Team, I have a scenario like this. To configure the destination of the GRE tunnel, specify the IP address of the remote device in the tunnel-destination command. At a minimum, for this interface, you must configure an IP address, enable the interface, and set it to be a tunnel interface. Note that the configuration commans will be the same for all Cisco routers like Cisco … The list of available templates are the ones that you have previously created. You can monitor transport circuit bandwidth on vEdge routers and on vManage NMSs. If the configuration named *.cfg is available in NVRAM storage or flash storage, IOS will perform a backup of the original configuration and boots up using this configuration. To display the hardware present in the router, use the show hardware inventory command: To display the actual speed of each interface, use the show interface command. In both configuration commands, the bandwidth can be from 1 through 2147483647 (232 / 2) – 1 kbps.
