showing all possible AS-paths?
Hello Bird-users, Is there a way to get all route AS-path's information , and not just the slected path? either all, or just a specific route? I can see all routes, with it's selected path, but not (or don't know how to do it) all possible AS-path's. Thanks in advance Regards, -- Arjan Filius mailto:iafilius@xs4all.nl

I don't undestand you problem. If you get a specific route from two (or more) different BGP protocols, all instances are stored in routing table. By 'show route all' you can see all the paths. Look at this example. bird> show route 217.31.192.0/20 217.31.192.0/20 via 194.50.100.3 on eth1 [R25192x2 May05] * (100) [AS25192i] via 194.50.100.13 on eth1 [R25192x1 14:56] (100) [AS25192i] bird> show route 217.31.192.0/20 all 217.31.192.0/20 via 194.50.100.3 on eth1 [R25192x2 May05] * (100) [AS25192i] Type: BGP unicast univ BGP.origin: IGP BGP.as_path: 25192 BGP.next_hop: 194.50.100.3 BGP.med: 0 BGP.local_pref: 100 BGP.atomic_aggr: BGP.aggregator: 217.31.205.209 AS25192 BGP.community: (0,39392) via 194.50.100.13 on eth1 [R25192x1 14:56] (100) [AS25192i] Type: BGP unicast univ BGP.origin: IGP BGP.as_path: 25192 BGP.next_hop: 194.50.100.13 BGP.local_pref: 100 BGP.community: (0,39392) bird>

Hello Ondrey, yes it's clear, just cant get all AS paths behind your neighbors, just selected. So i assume to get that information i need to use provided looking glasses of the neighbors. Many Thanks again. Regards, Arjan Filius On Wed, 2010-06-23 at 09:09 +0200, Ondrej Filip wrote:
