Scenario: 6509-3BXL receiving 2 full tables. Problem: Outbound traffic imbalance
Feed 1 (AS1 in this example): Direct to tier-1 provider Feed 2 (AS2 in this example): Colo/house 'mix' of about 5 providers Outbound traffic pretty much all goes out feed 1. BGP tables from each provider are nearly identical, so the router is either choosing the lowest router-id, or shortest BGP path..even if I prepend the inbound on feed 1 I'm still seeing most/all traffic leave feed 1... any advice on getting traffic to balance without static route-maps? I'm perfectly happy if odd/even AS's were pref'd to one or the other...anything BGP based. Regex on the inbound route-maps? Example of something that might work? Thanks in advance... ##Current config: router bgp xxxxx no synchronization bgp log-neighbor-changes bgp update-delay 90 redistribute static route-map STATIC-TO-BGP neighbor x.x.x.1 remote-as 1 neighbor x.x.x.1 soft-reconfiguration inbound neighbor x.x.x.1 prefix-list ADVERTISE out neighbor x.x.x.1 route-map TRANSIT-1-IN in neighbor x.x.x.1 route-map TRANSIT-1-OUT out neighbor x.x.x.2 remote-as 2 neighbor x.x.x.2 soft-reconfiguration inbound neighbor x.x.x.2 prefix-list ADVERTISE out neighbor x.x.x.2 route-map TRANSIT-2-IN in neighbor x.x.x.2 route-map TRANSIT-2-OUT out no auto-summary route-map TRANSIT-1-IN permit 10 set as-path prepend last-as 1 ! route-map TRANSIT-1-OUT permit 10 set as-path prepend xxxxx ! route-map TRANSIT-2-IN permit 10 ! route-map TRANSIT-2-OUT permit 10 ! _______________________________________________ cisco-nsp mailing list [email protected] https://puck.nether.net/mailman/listinfo/cisco-nsp archive at http://puck.nether.net/pipermail/cisco-nsp/
