Hi,
I have a network with MPLS VPN L3, i am using Cisco CRS like P and ASR9000 for PE. I try to hide my links between PE - P and P - P, so i configured in my network mpls ip-ttl-propagate disable forwarded. The problem that i have now, is when i make a traceroute from a CE to another CE, the Egress PE does not respond the icmp unreachable with a source IP in the VRF, instead of this the source IP is the IP that i have assigned to the pe in the link between P and PE.
#traceroute 192.0.2.6
1 192.0.2.1 4 msec 0 msec 0 msec
2 10.0.0.10 4 msec 0 msec 4 msec
3 192.0.2.6 4 msec 0 msec 0 msec
If i try the same configuration in a testing network with IOS instead of IOS XR, the egress PE respond with an IP asiggned to a VRF interface like i hope.
#traceroute 192.0.2.6
1 192.0.2.1 4 msec 0 msec 0 msec
2 192.0.2.5 4 msec 0 msec 4 msec
3 192.0.2.6 4 msec 0 msec 0 msec
I attached the topology that i am using
I will appreciate if someone could help me.
Regards
José

What version are you runing?.
Can you try "icmp ipv4 source vrf" and try the trace again?.
