Cisco Cisco IOS Software Release 12.2(33)SRE

The following examples show how to use the VRF CLI provided by the MPLS VPN—VRF CLI for IPv4 
and IPv6 VPNs feature to migrate from a single-protocol VRF to a multiprotocol VRF configuration:

 multi-af-mode {common-policies 

| non-common-policies} [vrf vrf-name]

Router(config)# vrf upgrade-cli multi-af-mode 

common-policies vrf vpn4

Upgrades a VRF instance or all VRFs configured on the 
router to support multiple address families under the same 
VRF.

The multi-af-mode keyword specifies an upgrade of a 
single-protocol VRF or all VRFs to a multiprotocol 
VRF that supports multi-AFs configuration.

The common-policies keyword specifies to copy the 
route-target policies to the common part of the VRF 
configuration so that the policies apply to all address 
families configured in the multi-AF VRF.

The non-common-policies keyword specifies to copy 
the route-target policies to the IPv4 address family part 
of the VRF configuration so that the policies apply only 
to IPv4.

The vrf keyword specifies a VRF for the upgrade to a 
multi-AF VRF configuration.

The vrf-name argument is the name of the 
single-protocol VRF to upgrade to a multi-AF VRF 
configuration.

Router(config)# exit

Exits to privileged EXEC mode.

[vrf-name]

Router# show running-config vrf vpn4

Displays the subset of the running configuration of a router 
that is linked to a specific VRF instance or to all VRFs 
configured on the router.

The vrf-name argument is the name of the VRF of 
which you want to display the configuration.

The Cisco IOS image that supports the 
multiprotocol VRF commands might not support 
the show running-config vrf command. You can 
use the show running-config command instead.
