Hello. We've stumbled across a problem with a router manufacturer, which won't implement support for /127 prefix lengths. Now, we do have peering/transit partners using /127 on their p2p links. The result is that we either cannot peer with them, or will have to get new routers. RFC 3627 states that /127 is considered harmful, however I do feel this RFC confuse people since it doesn't propose a definite solution. It suggests a number of solutions and indicates using /64 is the right thing. I must say I strongly disagree on that conclusion. Wasting so much address space on point to point links just makes no sense to me. So I'm not sure what to do here. I have to convince someone; either our partners or the router manufacturer. I have the impression that /127 is used widely out there. -- Vegard Svanberg <vegard at svanberg.no> [*Takapa at IRC (EFnet)]
