Fabric Extend - cannot get adjacency over IP Tunnel

Fabric Extend - cannot get adjacency over IP Tunnel

Unsuccessfully cannot get an adjacency in GNS3 VOSS 7.0 using Fabric Extend over IP Tunnel using loopbacks. Can anyone advise where I’m going wrong here? I think my logic is correct, but maybe the config is not? I need to implement this for a customer, I thought I would try this in a lab scenario to test the feature, but not getting anywhere with it.

Here's my topology:

good point, if MTU is not sufficient, we don't allow the IS-IS session to come up.

If isp supports MTU greater than 1594, without ONA, how to configure vsp4k?

May be you are hitting MTU problem. Make sure the switch in-between supports more than 1600 bytes of MTU size.

Still no luck. If I directly attach the 8k's - adjacency comes up. If I put a switch inbetween, nothing.
