NEVER EVER EVER put an IX prefix into BGP, IGP, or even static route. An IXP LAN should not be reachable from any device not directly attached to that LAN. Period. Doing so endangers your peers & the IX itself. It is on the order of not implementing BCP38, except no one has the (lame, ridiculous, idiotic, and pure cost-shifting BS) excuse that they "can't" do this.
Hi Patrick, I have to disagree with you. If it appears in a traceroute to somewhere else, I'd like to be able to ping and traceroute directly to it. When I can't, that impairs my ability to troubleshoot the all too common can't-get-there-from-here problems. The more you hide the infrastructure, the more intractable problems become for your customers. The IXP LAN should be reachable from every device on the ASes which connect to it, not just the immediate router. Regards, Bill Herrin -- William D.
