OK, so I finally get all my routers talking BGP in my new setup. ( time
consuming. I will never complain about my isp again. Bridges for sale. Cash
only ;-> )
Right now everything is happy, in part because I have an igp running on al
routers, so there are no reachability issues.
Question - next-hop-self - necessary only if there are no igp or static
routes between bgp neighbors?
Situation: I have an AS consisting of two routers, each of which is
connected to an AS consisting of one router. I am playing ISP god, and doing
static routes between one-router AS and two-router AS. When I made that
change on all routers, the 1-router AS routes now appear in all other
routing tables as BGP routes. There continues to be full reachability among
all routers. Prior to the static route experiment I saw all routes as IGP
routes in the routing table.
Question - in this situation, what is the behavior I am seeing? Even though
BGP has....
Oh, now I get it. Never mind.
The phenomenon I am seeing is this: external BGP routes have an AD of 200.
The IGP routes have a lower AD, and therefore are placed into the routing
table. THINK!!!! Gotta THINK!

A long shot at passing is better than no shot.
Right now that's all I got to get me through,
So I gotta believe!
