2006年1月30日 · The MPLS VPN—Show Running VRF feature provides a Cisco IOS command-line interface (CLI) option to display a subset of the running configuration on a router that is linked to a Virtual Private Network (VPN) routing and forwarding (VRF) instance. You can display the configuration of a specific VRF or of all VRFs configured on a router.

To set an address family ipv4 in vrf configuration mode use the address-family ipv4 command. To remove the IPv4 address-family, use the no form of this command. A standardized exterior gateway protocol designed to exchange routing and reachability information. IP address of the next hop in the traffic flow.

VRF stands for Virtual Routing Forwarding. Virtual routing and forwarding. VRFs are like VLANs for routers, instead of using a single global routing table we can use multiple virtual routing tables. Each interface of the router is assigned to a different VRF.

2013年8月8日 · if you issue "sh ip route" this will show you all the interfaces, vlans, routes in global routing table. If you want to see routes, vlans, etc.. in a specific vrf then you issue this command: sh ip route vrf RC. HTH. Reza

2018年4月11日 · Do you have any VRFs configured on your switch? sh ip vrf. The command sh ip arp will only show the arp cache for the default VRF. There is a good chance this vlan belongs to a different VRF. Under the L3 interface configuration for the subnet in question there should be a line: ..include the 'xxxx' into the follow command: sh ip arp vrf xxxx.

To create a VRF, enter the following command in global configuration mode. VRF is configured with an arbitrary name. Then, the Route Distinguisher (RD) ensures that the address space does not overlap with the global and other VRFs.

show ip route vrf * displays the global routing table plus all the VRF instances. sh ip route vrf * 0.0.0.0 displays the default route for each VRF. This shows the default route for each VRF, including the default VRF.

You need to issue the show bgp vrf [VRF-NAME] all summary command to view the same information as you would with the show bgp summary command but specific for the VRF in question.

The following examples show how to create VRFs for the examples in this document. In each VRF example, a VRF instance is created and then an interface in the VRF space is created for each entity in the communication loop. An OSPF is configured for the VRF to enable routing exchanges between the two entities.

In this tutorial, we will discuss traffic isolation at Layer3 level using VRF Lite on Cisco routers. VRFs employ essentially the same concept as VLANs and Trunking, but at Layer 3. VRF (Virtual Routing and Forwarding) is traditionally associated with IP MPLS technology whereby an ISP creates Layer3 (or Layer2) VPNs for customers using VRF.
