I have 2 routers here that seem to have good mp-bgp neighboring, one IOS, and the other IOS XRv. I config'd both to be a route reflector cluster. They are both advertising routes to each other but for some reason, R5 isn't rcv'ing the routes from R2-xr
Shown below you will see the R2-xr is sending the routes, but I don't see them come into R5. I show some debugs from R5 to help determine why.
