Converting IP VRF To VRF Defination Using IOS

Earlier
=====

R1#sh run | s vrf

ip vrf ABC

 rd 1:1

 route-target export 1:1

 route-target import 1:1

####################

R1(config)#vrf upgrade-cli multi-af-mode ?

  common-policies      IPv4 VRF policies are moved to common VRF policies

  non-common-policies  IPv4 VRF policies are not moved to common VRF

                       policies,but kept as ipv4 only VRF policies.

R1(config)#vrf upgrade-cli multi-af-mode common-policies

You are about to upgrade to the multi-AF VRF syntax commands.

You will lose any IPv6 address configured on interfaces

belonging to upgraded VRFs.

Are you sure ? [yes]: yes

Number of VRFs upgraded: 1

Later

====

R1#sh run | s vrf

vrf definition ABC

 rd 1:1

 route-target export 1:1

 route-target import 1:1

 !

 address-family ipv4

 exit-address-family

The prime reason you would want to do this possibly IPv6 introduction for PE-CE (6PE or 6VPE) since traditional " ip vrf " syntax doesn't natively support IPv6.

HTH...
