Case 9
只过滤来自AS 200的BGP路由:
路由器C配置如下:
!
- a: v8 a: ~/ Dneighbor 3.3.3.3 remote-as 200
neighbor 2.2.2.2 remote-as 100
neighbor 2.2.2.2 filter-list 1 out
) H) q, @) ?/ r. @8 G1 m5 w!
ip as-path access-list 1 deny ^200$
2 G( F: k; ?$ `$ U3 o: O8 L3 e" c, oip as-path access-list 1 permit .*
3 F& r5 ]* D+ L& ]8 u!
Route Map Filtering
使用route map过滤BGP路由:
4 |4 l4 {8 ~4 i" q: ?! x% J/ Z$ nAiko(config-router)#neighbor {ip-address} route-map {map-name} {in|out}
