Multi-Site connectivity from Spine

[david.j.evans]

Hi All,

We're setting up a new environment with two sites and using Cisco Multi-Site to allow for Stretched EPGs across the sites.

The APICs are both setup and the Multi-Site cluster is ready with sites added, a test tenants created and schema deployed.

The issue we have is that the Spine port 1/65  (9364s) is connected to the ISN, but is not finding an OSPF neighbors, and can't even ping the other side if the /30 subnet.

Viewing information from a tcpdump, the multicast traffic is visible from both interfaces, but dropped on the ACI fabric (meaning layer 1 is right, and physical components are functioning).

Any thoughts or experience welcome - hoping it's just an ACI setting that was missed.

Hi David

Can you post 

show ip interface brief vrf overlay-1 and
show ip ospf interface vrf overlay-1 from the spine

and the equivalent  show commands from your ISN-device?

Update: The issue was due to a firmware issue that stopped port 1/65 from being used. Upgrading to version 13.2(2l) solved the issue.
