Public IP: 193.188.XX XX. When the router transmits or receives traffic, it distributes traffic flows evenly among the tunnels, using ECMP. The system IP address can be any IPv4 address except for,, and, and and later. The interface is the GRE interface in VPN 0 that is used to reach the service. You can link a PPP interface to only one physical interface on a vEdge router, and you can link a physical interface to only one PPP interface. Following are the important physical interfaces in a Cisco Router. To limit the remote TLOCs that the local TLOC can establish BFD sessions with, mark the TLOC with the restrict option. vEdge(config-tunnel-interface)# color color [restrict] Cisco 800M Series ISR Software Configuration Guide, View with Adobe Reader on a variety of devices, View in various apps on iPhone, iPad, Android, Sony Reader, or Windows Phone, View on Kindle device or Kindle app on multiple devices. 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. When the weight value is higher, the router sends more traffic to the TLOC. You do this using the mtu command. A highly available Viptela network contains two or more vSmart controllers in each domain.

To use vManage templates to configure PPPoE on vEdge routers, you create three feature templates and one device template: To create a VPN-Interface-PPP feature template to configure PPP parameters for the PPP virtual interface: Enter a description for the PPP virtual interface. Enters configuration mode for the loopback interface. A valid configuration file can be created by saving the running configuration of a router to flash, USB flash, or to a TFTP Server. Specifies the static route for the IP packets. You can change the traffic distribution by modifying the preference or the weight, or both, associated with a TLOC. Enter a name and description for the device template. vEdge(config-interface-ge)# vrrp group-number. Cisco 1000 Series Connected Grid Routers; Configure  < Return to search results. When PMTU discovery is enabled, the device to automatically negotiates the largest MTU size that the interface supports in an attempt to minimize or eliminate packet fragmentation: On vEdge routers, the Viptela BFD software automatically performs PMTU discovery on each transport connection (that is, for each TLOC, or color). 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. You start the process of configuring router Ethernet interfaces by making a physical connection to your router. The hello tolerance interval must be at most one-half the OMP hold time. On a vEdge router, you can configure up to seven tunnel interfaces. For the tunnel interface, you can configure a static IPv4  address, or you can configure the interface to receive its address from a DHCP server. A sub-interface in a Cisco Router uses the parent physical interface for sending and receiving data. Each interface can be present only in a single VPN. vEdge(config-interface)# ip address prefix/length … At a minimum, for this interface, you must configure an IP address, enable the interface, and set it to be a tunnel interface. (For more information, see Configuring Control Plane and Data Plane High Availability Parameters.) Router(config-if)# ip address To explicitly configure BFD to perform PMTU discovery, use the bfd color pmtu-discovery configuration command. By default, the DHCP server on a single interface can assign 254 DHCP leases, and each lease is valid for 24 hours. How to configure WAN monitor in ManageEngine OpManager? vEdge-2(config-interface)# tloc-extension geslot/port 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. If you have configured a primary and a backup GRE tunnel, list the two GRE interfaces (grenumber1 grenumber2) in the service command. To generate notifications when the bandwidth of traffic received on a physical interface exceeds 85 percent of a specific bandwidth, configure the downstream bandwidth: vEdge/vManage(config)# vpn vpn-id interface interface-name bandwidth-downstream kbps. vEdge(config-dhcp-server)# offer-time minutes. vEdge-1(config-interface)# mtu number The VLAN number, vlan-number, can be in the range 1 through 4094. If the physical interface goes down for any reason, all its subinterfaces also go down. Step 4. To override the speed negotiated by the two devices on the interface, disable autonegotiation and configure the desired speed: vEdge(config-vpn)# interface interface-name no autonegotiate To configure multiple PPPoE-enabled interfaces in VPN 0, click the plus sign (+) next to Sub-Templates. To configure static routes, perform these steps in global configuration mode. Optionally, create a VPN feature template to modify the default configuration of VPN 0. Span a WAN interface on a router I have a router with 3 interfaces. At a minimum, for these interfaces, you must configure an IP address, and you must enable it: Viptela(config)# vpn number 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. To generate notifications when the bandwidth of traffic transmitted on a physical interface exceeds 85 percent of a specific bandwidth, configure the upstream bandwidth: vEdge/vManage(config)# vpn vpn-id interface interface-name bandwidth-upstream kbps. Video learning.This video will show you how to configure Cisco router 2821 to access the internet.If you want to see more videos, please subscribe this video. In this process, all the interfaces begin the process of establishing control and BFD connections. The feature also requires that a valid configuration file, with the filename extension.cfg, is stored in the USB flash drive. On vEdge-1, we see no BFD sessions to vEdge-2 (system IP address 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. GRE interfaces do not support cFlowd traffic monitoring. When the router transmits or receives traffic, it sends the traffic only to the TLOC with the highest preference. Viptela(config-vpn)# interface interface-name arp ip ip-address mac mac-address. In practice, you always configure additional parameters for each interface. 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. vEdge-1(config-interface)# no shutdown 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]. The group number identifies the virtual router. Then, create a data policy on the vSmart controller that applies to the service VPN. Router(config)# interface FastEthernet 0/0 Router(config-if)# Once in interface configuration mode you use the command syntax ip address n.n.n.h s.s.s.m; to complete the first lab objective we’ll need to execute the ip address from the FastEthernet0/0 interface configuration mode as shown below; To see this configuration use the show running-config command, beginning in privileged EXEC mode. An interface on a router that connects to the Internet Service Provider (ISP) is often configured as a DHCP client. Exits configuration mode for the loopback interface and returns to global configuration mode. The following output shows the control connections on vEdge-1 in a network with two vSmart controllers: You can verify that the two vEdge routers have established no BFD sessions between them. You can configure one or two GRE interfaces per service. Step3: Configure IP addresses for Router Interfaces. The autonomous-system number identifies the route to other EIGRP routers and is used to tag the EIGRP information. You can monitor transport circuit bandwidth on vEdge routers and on vManage NMSs. 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. You cannot use this same address for another interface in VPN 0. Command descriptions: ip address: Adds an address and subnet mask to the interface. vEdge(config-interface)# tunnel-interface 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. By default, Viptela devices send a Hello packet once per second to determine whether the tunnel interface between two devices is still operational and to keep the tunnel alive. On vEdge routers, interface-name can be either geslot/port or loopbacknumber. Color is a Viptela software construct that identifies the transport tunnel. Enters router configuration mode, and enables EIGRP on the router. You can monitor the bandwidth usage on a transport circuit, to determine how the bandwidth usage is trending. Click No to enable the PPP virtual interface. For example: To view PPPoE session information, use the show pppoe session command. exit: Switches to the previous mode. 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. Hi All, I am planning to implement one new cisco 1921 router in our office. The default administrative distance of routes learned from DHCP is 1. In the Additional VPN 0 Templates section to the right of VPN 0, click the plus sign (+) next to VPN Interface PPP. 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. If the PPPoE server does not specify a maximum receive unit (MRU), the MTU value for the PPP interface is used as the MRU. To use DHCP, select Dynamic. For example, if TLOC A has weight 10, and TLOC B has weight 1, and both TLOCs have the same preference value, then roughly 10 flows are sent out TLOC A for every 1 flow sent out TLOC B. (Note that you cannot disable keepalives by issuing a no keepalive command. Tunnel interfaces on vEdge routers must have an IP address, a color, and an encapsulation type: vEdge(config)# vpn 0 Let me show you how to configure it: I’m using two routers connected to each other with a serial link. To take WAN side connectivity into account for VRRP, you can configure one of the following: As discussed above, the IEEE 802.1Q protocol adds 4 bytes to each packet's length. 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. Ensure that you select templates for all mandatory feature templates and for any desired optional feature templates. If you press the push button for more than three seconds and then release the push button after IOS is up and running, IOS detects this event and looks for configuration files in the order of priority.If the IOS finds the configuration file, it copies the configuration file to the startup configuration file. Hi Team, I have a scenario like this. In this way, you extend the WAN transport VPN so that both routers can establish tunnel interfaces, and hence can establish independent TLOCs, in the overlay network. Example: Router(config)# interface gigabitethernet 0/8 . For subinterfaces to work, you must configure the physical interface in VPN 0 and activate it with a no shutdown command. For IPsec encapsulation, the default MTU is 1442 bytes, and for GRE it is 1468 bytes, These values are a function of overhead required for BFD path MTU discovery, which is enabled by default on all TLOCs. For a secure connection, type vEdge(config-interface-gre)# (tunnel-source ip-address | tunnel-source-interface interface-name) I'm new to the Cisco world, and I'm trying to set up the router with an existing broadband cable connection. Step 3 2 G/E interfaces and 1 T1 (serial interface) for a MPLS link. In the Viptela software, you configure VRRP on an interface, and typically on a subinterface, within a VPN. You can also explicitly disallow services by including the no allow-service command. You can modify this on an interface: The MTU can range from 576 through 1804 bytes. On vEdge routers, you must configure the tunnel encapsulation. In these cases, the interface used by the protocol must be the same as one of the interfaces configured in the VPN. Configure a tunnel interface for the PPP interface: Optionally configure the name of the access concentrator used by PPPoE to route connections to the internet: Link a physical Gigabit Ethernet interface in VPN 0 to the PPP interface: Enable the physical Gigabit Ethernet interface to be operationally up: If your ISP requires that you configure profile properties, configure one or more of the following: For cellular interfaces, you must use a DHCP client to dynamically configure the IP address. VPN 0 is the WAN transport VPN. 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. The ARP entry maps an IP address to a MAC address. Serial interfaces are used to communicate with other local Cisco Routers or to establish a connection to the WAN through a CSU/DSU device. You can see this by using the details filter with the show running-config command. Enters router configuration mode, and enables RIP on the router. To display information about the system interface, use the show interface command. If the primary tunnel comes back up, all traffic is moved back to the primary GRE tunnel. MORE READING: How to Configure DHCP on Cisco 851 or 871 Router Each TLOC is uniquely identified by a 3-tuple comprising the system IP address, a color, and an encapsulation. When the DHCP server at the vEdge router's local site is on a different segment than the devices connected to the vEdge router or than the vEdge router itself. Exits configuration mode for the GE interface and returns to global configuration mode. Static routes provide fixed routing paths through the network. 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. 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”). In the right pane, select the VPN template. PPPoE-enabled physical interfaces do not support: The Viptela implementation of PPPoE does not support the Compression Control Protocol (CCP) options, as defined in RFC 1962. an Internet connection with a static address As with all interfaces, the subinterface must be activated, by configuring it with the no shutdown command. The rx-kbps and tx-kbps fields in this command shows the current bandwidth usage on the interface. For some reason if second core takes more time, system reports an error message and continues the normal start up. The default hello interval is 1000 milliseconds, and it can be a time in the range 100 through 600000 milliseconds (10 minutes). For more information, see Configuring Localized Data Policy. Because the router vEdge-2 connects to two transports, we create subinterfaces between the vEdge-1 and vEdge-2 routers. To configure an interface as a DHCP helper, configure the IP address of the DHCP server on the interface that connects to the local site's network: vEdge(config-vpn)# interface geslot/port dhcp-helper ip-address. 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. The EIGRP autonomous system number is 109. To configure Gigabit Ethernet (GE) WAN interfaces, follow these steps, beginning in global configuration mode. Viptela(config-interface)# no shutdown. On the remote vEdge router, you must configure the same tunnel encapsulation type or types so that the two routers can exchange data traffic. For example: In this output, a port type of "transport" indicates that the interface is configured as a tunnel interface, and a port type of "service" indicates that the interface is not configured as a tunnel interface and can be used for data plane traffic. 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 vEdge-1(config-tunnel-interface)# color color. 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. One special use of loopback interfaces is to configure data traffic exchange across private WANs, such as MPLS or metro Ethernet networks. This tutorial explains how to configure a Cisco router step by step. 1) Configure each WAN interface to connect to each ISP, respectively: interface FastEthernet 0/0 description primary-WAN ip address For a VRRP interface to operate, its physical interface must be configured in VPN 0: vEdge(config-vpn-0)# interface ge-slot/port You can optionally configure an IP address for the GRE tunnel itself: vEdge(config-interface-gre)# ip address ip-address. Configuring the first router. 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. Each device in the overlay network must have a unique system IP address. To display TLOC information, use the show omp tlocs command. In the action portion of the data policy, you must explicitly configure the policy to service the packets destined for the GRE tunnel. During this shutdown process, the circuit of last resort triggers a BFD TLOC Down alarm and a Control TLOC Down alarm on the vEdge router. The NAT configuration is required because the two vEdge routers are sharing the same transport tunnel. With these default values, if no Hello packet is received within 11 seconds, the tunnel is declared down at 12 seconds. Because VRRP runs on a LAN interface, if a vEdge router loses all its WAN control connections, the LAN interface still indicates that it is up even though the router is functionally unable to participate in VRRP. For example: For some protocols, you specify an interface as part of the protocol's configuration. Create a VPN-Interface-PPP-Ethernet feature template to configure a PPPoE-enabled interface. Configure a NAT on the public-network-facing interface on the vEdge router. The encapsulation can be either IPsec or GRE. Notifications are sent as Netconf notifications, which are sent to the vManage NMS, SNMP traps, and syslog messages. Set up your system as a DHCP client to obtain the IP address of the router automatically. After you establish the connection, you can proceed with the basic configuration of Ethernet, Fast Ethernet, or Gigabit Ethernet connections. By default, all interfaces have an MTU of 1500 bytes. Select the PPP tab, and in the AC Name field, enter the name of the the name of the access concentrator used by PPPoE to route connections to the Internet. You can configure up to four IP addresses, and the addresses must be entered in a single dhcp-helper command. For more information, see Unicast Overlay Routing Overview. For each VRRP interface (or subinterface), you assign an IP address and you place that interface in a VRRP group. Click the arrow pointing right to move the device to the Selected Device(s) column on the right. If that tunnel fails, all packets are then sent to the secondary tunnel. The PPPoE server component is not supported. The tloc-extension command creates the binding between the non-connected router and the WAN or private network. View this content on vEdge(config-tunnel-interface)# [no] allow-service service. 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. One subinterface binds to the Internet circuit, and the second one binds to the MPLS connection. Step 2: Select the interface … Enters global configuration mode, when using the console port. Enter the name of the physical interface in VPN 0 to associate with the PPP interface. Depending on the routing protocol you are using, enable either OSPF or BGP service on the non-connected router interface so that routing between the non-connected and the connected routers comes up. You con configure Serial, 3G/4G, Ethernet, or Broadband (xDSL) as a secondary WAN depending on the WAN types supported by the router. vEdge(config-dhcp-server)# options domain-name domain-name Note that this is not the same as a loopback address that you configure for an interface. This means that each vEdge router can have up to seven TLOCs. The Viptela software automatically selects the correct tunnel on the destination vEdge router. On a vEdge router, services that you configure on a tunnel interface act as implicit access lists (ACLs). For more information, see Configuring Centralized Data Policy. Push button can be useful for recovery during one of the two scenarios: Table 2-1 shows the high level functionality when the push button is pressed during ROMMON initialization. The clock rate will set the speed. 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. GRE interfaces are logical interfaces, and you configure them just like any other physical interface. The cellular module provides wireless connectivity over a service provider's cellular network. To avoid loading an incorrect.cfg file, ensure that there is only one.cfg file in the USB flash drive. When you configure two, the first interface is the primary GRE tunnel, and the second is the backup tunnel. Step 6. It can be up to 2048 alphanumeric characters. You use a loopback interface because it is always reachable when the router is operational and when the overlay network is up. vSmart(config)# vpn 0 The interfaces that participate in a VPN are configured and enabled in that VPN.
