We tried using .255/32 as a loopback address, but certain Cisco routers (even running pretty modern code) refused to accept it as anything other than a directed broadcast address, even when they had the /32 in their rib learned via igp. Getting back replied from unrelated interfaces when trying to ping a neighboring router loopback got real old real quick. God only knows what the more obscure and/or less service provider tested platforms will do when confronted with these things, which is one of the biggest issues with enabling such new (yes I know it's actually quite old, but never underestimate the incompetency of people) features. For example, last I looked Foundry/Brocade puked if it so much as received a /31 via a routing protocol, which made it a real problem if you ran /31s and ever needed to add one of those boxes to your network later on. -- Richard A Steenbergen <[email protected]> http://www.e-gerbil.net/ras GPG Key ID: 0xF8B12CBC (7535 7F59 8204 ED1F CC1C 53AF 4C41 5ECA F8B1 2CBC) _______________________________________________ juniper-nsp mailing list [email protected] https://puck.nether.net/mailman/listinfo/juniper-nsp
