Making that particular error essentially > self-correcting, For Locally Assigned ULA you default to filtering *all* prefixes. ULA is not the same as GUA. You can't just plug sites together without *first* checking for collisions in ULA space like you can with GUA. It is a recipe for disaster if you don't check. A-B-C-A will work if you just want to talk to your direct neighbors. If it is a federation you need to get one or both of the A's to renumber and you also need someone/thing to ensure uniqueness within the federation. > Bill Jouris > Inside Products, Inc. > www.insidethestack.com > 831-659-8360 > 925-855-9512 (direct) -- Mark Andrews, ISC 1 Seymour St., Dundas Valley, NSW 2117, Australia PHONE: +61 2 9871 4742 INTERNET: marka@isc.org
