Let's say I wanted to send traffic to even AS's out peer 1 and odd AS's out peer 2.
Am I crazy? (Seems better than using metrics based solely on static IP ranges...) Would this work? route-map TRANSIT-1-IN permit 10 set as-path prepend last-as 1 ! route-map TRANSIT-1-IN permit 20 match as-path 105 set local-preference 210 ! route-map TRANSIT-2-OUT permit 10 set as-path prepend xxxxx ! route-map TRANSIT-2-IN permit 10 match as-path 106 set local-preference 210 ! route-map TRANSIT-2-OUT permit 10 ! ip as-path access-list 105 permit [02468]$ ip as-path access-list 106 permit [13579]$ On Mon, May 17, 2010 at 10:59 AM, Anton Kapela <[email protected]> wrote: > On Mon, May 17, 2010 at 10:42 AM, Andrew Tolstykh <[email protected]> > wrote: > > Just a shot in the dark, but I don't see load balancing enabled in your > configuration snippet: > > > > router bgp xxxxx > > This question comes up semi-often, perhaps there ought to be a FAQ?
