Config remained pretty much the same (from L3VPNs perspective), but it looks like the behaviour of both platforms is somewhat different. I'm not sure if it's a feature or a bug yet. We have a typical setup, like this: CE1 --- PE1 --- P1 --- P2 --- PE2 --- CE2 | | + --- PE3 --- CE3 So customers site is multihomed via PE2 and PE3 and has internal connection between CE2 and CE3 With 7301 Traceroute from CE1 used to show the IP of PE2 or PE3 (egress interface from the vrf), after the upgrade to ASRs - all we can see is PE1's IP and then straight CE2/CE3, but since customer drops icmp packets - we can't really see which way it's really going. Is there a way to get an ICMP reply from the egress ASR? I understand it switches the packets out through the interface without actually doing any lookups, but even after forcing 'label-per-vrf' we can't see the last hop. Any ideas if this behaviour can be corrected? kind regards Pshem _______________________________________________ cisco-nsp mailing list [email protected] https://puck.nether.net/mailman/listinfo/cisco-nsp archive at http://puck.nether.net/pipermail/cisco-nsp/ _______________________________________________ cisco-nsp mailing list [email protected] https://puck.nether.net/mailman/listinfo/cisco-nsp archive at http://puck.nether.net/pipermail/cisco-nsp/
