Re: best practice for advertising peering fabric routes

* Patrick W. Gilmore:

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.

Any ideas why DE-CIX doesn't enforce this? One advantage is that IXP participants can perform emergency maintenance if they have isolated their IXP router from their own network.
