Description (partial)

When doing a traceroute in a VRF, the last hop PE may respond with the ICMP ttl exceeded using its MPLS core facing interface instead of an IP address in the VRF.

This is observed when doing a traceroute to a BNG subscriber in a VRF and with 'icmp ipv4 source vrf' configured on the router.
