Description (partial)

The MKA session may not come up on the N7k/N77 when the key-server priority on the remote ASR9k/1k/Cat9k is increased on the fly to make the Nexus device as the key-server.

N7k/N77 begins as a member in a secure session where the ASR 9k/1k/cat9k is the key-server.
Key-server priority on the remote device is increased on the fly causing the N7k/N77 to automatically get elected as the key-server.
N7k/N77 may show itself as the key-server now, but the session remains in pending state and the link is not secured and the traffic fails.
