Hello community
I'm trying to configure OTV on my lab with Cisco Csr1000v version (17.3.4a), I have 4 routers ( 2 on each site), when I do "show otv detail", I get this output:
CSR-1#show otv detail

It seems like there's a problem in connectivity between the 2 boxes in the same site over the site vlan
When I try "show spanning tree vlan 1111" I get this output:
CSR-1#show spanning-tree vlan 1111
VLAN1111
