I apologize as I am still trying to learn routing policies for Cisco. Does ISIS need a routing policy to accept routes from neighbors? Maybe I am thinking it is similar to JunOS. I am able to form an adj. between my iOS-XRv VM and my physical router. My physical router receives a route from the VM, however the VM does not receive any routes. If this is a route policy issue please advice.
