BGP route not advertised (inaccessible)
I don't get this. Most of the stuff I have been reading states that an inaccessible next-hop will prevent a BGP route from being advertised. Ok, so there must be some other reason for the "inaccesible" because the next-hop is in the routing table!

So, the question is: why is that "inaccesible" there?
