RE: Re: BGP and Admin Distance

   I think he is saying that R1 learns the route from AS254 with an admin
   distance of 20 then he redistributes it and r2 sees it as OSPF and
   advertises it to R3 with an admin distance of 110 (meanwhile R3 has
   learned the route via IBGP with an admin distance of 200). So the
   answer is:
   
   A) Stop redistributing it and let BGP do its thing (next-hop-self may
   be necessary, depending...)
   
   B) Change the admin distance of OSPF to 205 (generally frowned upon)

     Hi Ben
     I just received the other answers on this question!
     The most are good points, but what I'm still miss
     is the reason: Why would you like to see it as a
     BGP-Route in R3?

     If you have the following senario:
     
     (AS254)----|-R1--R2--R3-|
                 (AS5) (AS5)
     
     My routers are running OSPF.
     R1 and R3 are running BGP in AS5. R2 is not running BGP.
     A route coming from AS254 into AS5 (192.78.5.0) is redistributed at
     R1 into OSPF. The problem is that my routers see it as an OSPF
     route, not a BGP route, because of Admin Distance. What's the
     remedy?
     
     To see it as BGP-Routes, don't redistribute them to OSPF and run
     BGP everywhere.
     But I don't see any advantage of that!
     
     Thx,
