Yes, I've tried that too.. But what I am thinking of doing is, using a route-map/bgp-announcement based version of building 'prefix-list' or 'distribute-list' to decide whether to accept route or not..
But as you said, I don't think that is possible heh..
Foundry supports a feature called Cooperative BGP4 Route Filtering (http://www.foundrynetworks.com/services/documentation/ecmg/BGP4.html#63462) Some digging around at juniper.net reveals that Juniper also supports ORFs but only on the ERX platform (http://www.juniper.net/techpubs/software/erx/erx50x/swconfig-routing-vol2/ht... +bgp-config9.html). Cisco also supports it since 12.0 (http://www.cisco.com/en/US/products/sw/iosswrel/ps1612/products_feature_guid... +186a008008088c.html) It basically sends filters defined in prefix-lists in route refresh messages. A more formal definition of it can be found in the following draft (http://www.ietf.org/internet-drafts/draft-ietf-idr-route-filter-09.txt) -- Cliff Albert | RIPE: CA3348-RIPE | https://oisec.net/ cliff@oisec.net | 6BONE: CA2-6BONE | PGP Fingerprint = 9ED4 1372 5053 937E F59D B35F 06A1 CC43 9A9B 1C5A
