Hi there,
Unless I'm doing something really silly, I can't seem to get a multi-hop ebgp session up on an ASR9k. I'm wondering if anyone can spot something I might have overlooked or am just not aware of :
The neighbor reports:
BGP state = Idle (No route to multi-hop neighbor)
Which is odd because there is a route for this in the BGP table already. It's pingable, etc.
