Troubleshooting Command Difference Between VPNv4 and VPNv6

Few last posts (IPv6 Internet In VRF Over MPLS Cloud, IPv6 Addresing Architecture, IPv6 From MPLS But Not In VRF) are almost describing about IPv6 deployment. But currently most of the service providers are providing vpnv4 and every network operation engineer is well known to the troubleshooting and provisioning process. In this post, I am depicting about the basic command line difference between the configuration and troubleshooting of VPNv4 and VPNv6. Except vrf configuration rest all commands are same, only we need to use IPv6 instead if IPv4.
