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:
