BGP_as_path

BGP_as_path属于，路径越短越优先

1、抓取感应兴趣流

ip ip-prefix path1 index 10 permit 100.1.1.1 32 greater-equal 32 less-equal 32

2、建立路由策略

从R2方向来的路由

route-policy AS_PATH_P2 permit node 10  

if-match ip-prefix path1  

apply as-path 222 333 444 additive

从R3方向来的路由

route-policy AS_PATH_P3 permit node 10  

if-match ip-prefix path1  

apply as-path 666 additive

3、应用此策略导入

bgp 200

undo default ipv4-unicast

peer 12.1.1.2 as-number 100  

peer 13.1.1.3 as-number 100  

#

ipv4-family unicast

 undo synchronization

 peer 12.1.1.2 enable

 peer 12.1.1.2 route-policy AS_PATH_P2 import

 peer 13.1.1.3 enable

 peer 13.1.1.3 route-policy AS_PATH_P3 import
