Hi Experts,
I am wondering if some can explain me below scenario please
you have two routers in different DCs and they only have layer 2 connectivity, hence no the IP addresses assigned to their outside interface, they both have 1 loopback on each router and I want to form an adjacency between their loopbacks.
Can anyone explain, how to achieve this, or redirect me to the relevant cisco documentation please.
Solved! Go to Solution.

Hi,
We are talking about running a layer3 routing protocol between two DC. Do you have layer3 connectivity between them? Are you able to ping eachother loopback ips. I guess not. If they have layer2 connectivity, then physical port would be either access port or trunk port. In any case we can pass one vlan and configure a SVI interface (interface vlan <vlan-number>) for that vlan. Assign /30 ip address and over this you can have OSPF adjacency.
