What issue are you experiencing?

Router ID must config manually.

Add router ID then check leaking route

Hi @MHM Cisco World ,

In the test I just ran, it gives me the error message that the RID is not configured, but leaking still works despite of that message:

Router(config-router)#!
*Sep 19 12:54:41.826: %BGP-4-NORTRID: BGP could not pick a router-id. Please configure manually.

What IOS version are you using? I cut and pasted your configuration in 15.9(3)M4 and it works.
