Using IS-IS to run mpls rsvp under GNs3

browscofield — Tue, 27 Aug 2019 03:55:32 GMT

Hi guys,

I'm coming up ExtremeOS-VM over GNS3 using mpls and mpls-te under IS-IS, so, all routes are being received and sent to peers, however the interface tunnel is not getting up.
So, in this scenario I was using OSPF where it was working fine, so, I decided to try that other protocol, but the router A is not bring up the tunel interface with router B.

This scenario there are extreme and cisco, and the router A and B are cisco, and in the middle of the network are Extreme.
I have the follow message over wireshark

PATH ERROR Message :

As I said before, in the same scenario if I changed to ospf, everything worked properly.

Can someone inform if there would be some is-is limitation?

Cheers

Hello browscofield,

Did you check IS-IS/LDP configuration? It works without any issues on a real switches.

Best Regards,
