You can display the running configuration associated with a specific virtual routing and forwarding (VRF) instance or all VRFs on the device by entering the show running-config vrf command. To display the running configuration of a specific VRF, enter the name of the VRF as an argument to the show running-config vrf command. For example, for a VRF named vpn3, you enter:

Device# show running-config vrf vpn3

The show running-config vrf command displays the following elements of the running configuration on a device:

• The VRF configuration (This includes any configuration that is applied in the VRF submode.)

• The configuration of each interface in the VRF

Entering a show run vrf vpn-name command is the same as executing a show running-config interface type number for each interface that you display by use of the show ip vrf vpn-name command. The interfaces display in the same sorted order that you would expect from the show ip interface command.

For a channelized interface, the configuration of the controller is displayed (as shown by the show run controller controller-name command).

For a subinterface, the configuration of the main interface is displayed.

Open Shortest Path First (OSPF), Routing Information Protocol (RIP), Border Gateway Protocol (BGP), Enhanced Interior Gateway Routing Protocol (EIGRP), and static routing are routing protocols that support the virtual routing and forwarding (VRF) configuration.

OSPF has one process per VRF. The show running-config vrf command display includes the complete configuration of any OSPF process associated with the VRF. For example, the following shows the sample display for OSPF process 101, which is associated with the VRF named vpn3:

router ospf 101 vrf vpn3
 log-adjacency-changes
 area 1 sham-link 10.43.43.43 10.23.23.23 cost 10
 network 172.17.0.0 0.255.255.255 area 1

RIP, BGP, and EIGRP support VRF address-family configuration. If a VRF address family for the VRF exists for any of these routing protocols, a configuration in the following format is displayed:

router 
protocol
 {AS
 | PID
}
!
address-family ipv4 vrf
 vrf-name
.
.
.

Where the protocol argument is one of the following: rip, bgp or eigrp; the AS argument is an autonomous system number; the PID argument is a process identifier; and the vrf-name argument is the name of the associated VRF.

The following shows a sample display for a BGP with autonomous system number 100 associated with a VRF named vpn3:

!
router bgp 100
!
address-family ipv4 vrf vpn3
 redistribute connected
 redistribute ospf 101 match external 1 external 2
 no auto-summary
 no synchronization
 exit-address-family
 !

The show running-config vrf command also includes the configuration of any static routes configured in the VRF. For example:

ip route vrf vpn1 10.1.1.0 255.255.255.0 10.30.1.1 global 
ip route vrf vpn1 10.1.2.0 255.255.255.0 10.125.1.2 

Any element of a configuration that is not linked directly to a virtual routing and forwarding (VRF) instance is not displayed. In some instances, the display of the configuration of an element that is not directly linked to a VRF is required.

For example, the show running-config vrf command displays the configuration of an E1 controller whose serial subinterfaces are in a VRF. The command displays the controller configuration and the subinterface configuration.
