Hi guys,
The “show isis vrf TEST1 neighbor” command doesn’t show the ISIS neighbor at all, nevertheless ISIS routes are learns and installed in the routing table on both routers.
With the same ISIS configuration in the global routing table it is working fine, the “show isis neighbor” is showing the ISIS neighbor just fine.
See my configurations:
