OTV with CSR1K

dganta
Level 1
Level 1

Hi,

 

We are trying to use CSR1K to extend the Layer 2 using OTV between 2 private Datacenters, we have deployed evaluation AX license and tried to deploy the OTV solution though the join interface is reachable from the Datacenters we are observing that the OTV is not forming adjacency and also though the Internal vlan is extended using bridge domain .

 

I am getting the following error when I do show otv and also it is not forming OTV adjacency though the Join interface is reachable
