remember - a BGP speaker will only advertise routes that it actually uses (i.e. that it propogates its own routing table with). So in this case, you're peering router's routing table could be propogated with 50% sprint routes and 50% telia routes, so that if you block 1299, you only send the other 50% from telia to the customer. You could try setting your bgp max-paths to '2'. This way your routing table should include all routes learned from both providers. Then your permit _1299_ route-map should work.

I have two BGP connections to Tier-1 providers - Sprint and Telia (connected to separate routers). I have customer which wants full routing table from Telia. So I created filter-list : permit _1299_ which deny Sprint prefies, but now my customer receives only 50% prefixes :-( Is any solution for this problem ? best regards, Tommy Message Posted at: http://www.groupstudy.com/form/read.php?f=7&i=54201&t=54193 -------------------------------------------------- FAQ, list archives, and subscription info: http://www.groupstudy.com/list/cisco.html Report misconduct and Nondisclosure violations to [EMAIL PROTECTED]
