This feature provides Cisco IOS CLI commands that allow you to configure a multiprotocol VRF (IPv4 
and IPv6 VPNs in the same VRF) and to migrate a single-protocol VRF configuration (IPv4-only VRF) 
to a multiprotocol VRF configuration. 

A multiprotocol VRF allows you to share route targets policies (import and export) between IPv4 and 
IPv6 or to configure separate route-target policies for IPv4 and IPv6 VPNs. 

Perform the following tasks to configure or migrate to the MPLS VPN—VRF CLI for IPv4 and IPv6 
VPNs feature: 

 (required)

 (optional)

Perform the following task to migrate from a single-protocol VRF to a multiprotocol VRF configuration:

Perform the following task to configure a VRF for IPv4 and IPv6 VPNs. When you configure a VRF for 
both IPv4 and IPv6 VPNs (a multiprotocol VRF), you can choose to configure route-target policies that 
apply to all address-families in the VRF or you can configure route-target policies that apply to 
individual address families in the VRF. 

The following task shows how to configure a VRF that has that has route-target policies defined for IPv4 
and IPv6 VPNs in separate VRF address families.
