Kevin, you are correct, but let me add one detail...the first two checks BGP
makes are:
1. If the next hop is inaccessible, do not consider it.
2. If the path is internal, synchronization is enabled, and the route is
not in the IGP, do not consider the route.
So when A gets an update from B, A will allow the update to continue through
the best path selection algorithm if it passes both rules, but that does not
necessarily mean it will end up in the routing table. That determination is
based on whether it is the best path or not.

// thanks Kevin, Jack, Mark, Kvle, I think i got it, as a summary, could i und
erstand as below:
// A learns bgp routes from IBGP peer B, the bgp routes will enter into
toute table satisfy 2 conditions. first one is A should learn the routes throu
gh IGP, second is the next-hop address should already be in A's route table(whe
ther learned from IGP or BGP). is it correct?
