Hi Cisco gurus,
I have a network topology in this URL : http://www.4freeimagehost.com/show.php?i=3f0ac19164c9.png My first problem is in IGP configuration inside AS 100. I'm using OSPF. I still confused how to make non-BGP router (C,E,B,D) understand how route the packet transitting this AS. I have tried default route advertisement via OSPF, but since AS 100 is multihomed, there still any chance looping is happened there. How to configure it properly, without redistributing BGP route into OSPF. Second, I understand that iBGP inside AS 100 needs to be configured in mesh topology. Otherwise, use route reflector or confederation. But, if I use route reflector, I'm confused because the each route reflector itself must be meshed, in the other side, from the physical topology (as in the picture), there is none router that is connected mesh. So, which router should I choose as RR. Then, if I choose BGP confederation, still inside sub-AS the router must be connected in mesh topology, which impossible from the topology. So guys, what is your suggestion for my problem in IGP and iBGP configuration inside AS 100? I've read many books about BGP, particularly about transit AS, but their examples is always simple networks. I have found none complex case study network similar my topology. Thanks a lot. Every your comment, suggestion, criticism, will be very much appreciated. _______________________________________________ cisco-nsp mailing list [email protected] https://puck.nether.net/mailman/listinfo/cisco-nsp archive at http://puck.nether.net/pipermail/cisco-nsp/
