[R4-bgp-ipv4]peer 1.1.1.1 enable

查看BGP邻居的命令:

<R1>dis bgp peer ipv4

查看BGP路由表的命令:

<R1>dis bgp routing-table ipv4

指定源和目的ping:    ping -a 4.4.4.4 3.3.3.3   4.4.4.4为源,3.3.3.3为目的

BGP的负载均衡:

[R4]bgp 1000
[R4-bgp]address-family ipv4
[R4-bgp-ipv4]balance 2     可以负载两条路由

 

BGP路由的聚合:

[R2]bgp 1000
[R2-bgp]address-family ipv4
[R2-bgp-ipv4]aggregate 172.16.10.0 24 detail-suppressed  (抑制明细路由)

 

BGP路由属性:

本地优先级:(只在本地AS内有意义)

[R1]acl basic 2000
[R1-acl-ipv4-basic-2000]rule permit source 3.3.3.3 0

[R1]route-policy 1 permit node 1

[R1-route-policy-1-1]if-match ip address acl 2000
[R1-route-policy-1-1]apply local-preference 200   修改本地优先级为200
[R1-route-policy-1-1]quit
[R1]route-policy 1 permit node 2         route-map的空语句放行
[R1-route-policy-1-2]quit
[R1]bgp 1000
[R1-bgp]address-family ipv4
[R1-bgp-ipv4]peer 4.4.4.4 route-policy 1 export  出接口修改
