Hello, I feel that /26 is the smallest reasonable subnet size for an IXP, no matter how small the IXP is initially. If it starts growing, it will quickly grow past /27, but might just stay inside the /26. This is based on empirical experience over the decades. I do agree that it would be nice if the vendors took RFC 5549 seriously. A lot of IXPs would be ready to adopt it, if it was an option. It will create some headaches for route server scalability, but perhaps bird3 will fix those... anyway I digress... My two cents, PS. I don't think Tore appreciates how much more difficult it is to renumber an IXP compared to a data centre or an access provider. -- Aleksi Suhonen / TREX () ascii ribbon campaign /\ support plain text e-mail
