You make a great point..
This is basically a bog standard BGP test setup.. nothing else fancy added.. just verifying BGP works like v6.. except I can't use v6 because it's a CCR2216.. It's become apparent that there are some things still lacking, but I'm just trying to understand why whenever I force the session to resend or refresh routes it tears the connection down and never comes back.
