G'day! If the session doesn't establish, it won't have anything to do with the networks you are trying to advertise... Do routerOS logs give you any clues? If not, try adding bgp debug to system logging :) Cheers!

I'm able to ping across the CCR2004-16G-2S+ link no problem, however, the BGP session doesn't establish. I'm attempting to move an existing session from a /30 where it works in order to conserve IP space. Is there some skullduggery going on, or is 7.13 just not RFC3021-compliant?
