Setup GNS3 0.8.6
IOS: 12.2(33)SRE1
IOS-XRv: 5.1.1
I can’t ping R8 10.0.0.8 from R1 10.0.0.1. Looking at packet captures, I can see ARP requests from R1 hitting R2’s f1/0 and exiting R2’s f0/0.34 with a with labels 23, 16000. The pseudowire is up and connected. On R2 the send counters for the L2VPN are incrementing. On the XR, the receive counters are not incrementing. When I ping from R8 to R1, the XR counters don’t increment either. To test connectivity from XR1 to R8, I removed l2transport from the XR1 g0/0/0/1, enabled CDP and both devices could see each other. Pings worked too when g0/0/0/1 was setup with an IP address.
Is this an IOS-XRv bug? Or am I missing something?
Thanks for looking...
