So what did you decide, Andy? What are your greater concerns? Router failure? Link failure? How are all 4 connected without respect to BGP? In general, I'd just follow the physical topology unless there's a reason not to.

Hi, Hopefully a simple eBGP question: If I have 2 edge routers in an AS, and 2 edge routers in another AS is it best practices to have them in a square, or triangles? By this I mean AS1 has router 1 and router 2 (running iBGP between them), and AS 2 has the same. Is it best practice to have an eBGP peer between AS1 router 1 <-> AS2 router 1, and AS1 router 2 <-> AS2 router 2, or: AS1 router 1 peering with AS2 router 1 and 2, and AS1 router 2 peering with AS2 router 1 and 2. Either way, can somebody confirm the best practice and why? Any help would be greatly appreciated. All the best, Andy _______________________________________________ cisco-nsp mailing list [email protected] https://puck.nether.net/mailman/listinfo/cisco-nsp archive at http://puck.nether.net/pipermail/cisco-nsp/ _______________________________________________ cisco-nsp mailing list [email protected] https://puck.nether.net/mailman/listinfo/cisco-nsp archive at http://puck.nether.net/pipermail/cisco-nsp/
