I like would to know what are best practices for an internet exchange. I have some concerns about the following; Can the IXP members use RFC 1918 ip addresses for their peering?
No. Those IP addresses will at least appear on traceroutes; also, it might not be such a good idea to use the same RFC1918 space (accidentally) on different IXPs. This will get your skin crawling (thing IGP, or at least config databases)... IXPs can usually get a v4 and a v6 block for their peering grid easily.
Can the IXP members use private autonomous numbers for their peering?
They could, but what would you then do with them inside your IGP? And apart from that - ISPs that want to peer tend to have their ASNs ready... I am not an IXP operator, but I know of no exchange (public or private, big or closet-style) that uses private ASNs or RFC1918 space. Elmar.
