vrrp+去回同路

需求

1、数据路由去回同路

配置

R2配置：

1、选取网络

ip ip-prefix vrrp1 index 10 permit 10.1.1.0 24 greater-equal 24 less-equal 24

ip ip-prefix vrrp2 index 10 permit 20.1.1.0 24 greater-equal 24 less-equal 24

2、策略，apply配置cost值

route-policy vrrppolicy permit node 10  

if-match ip-prefix vrrp2  

apply cost 20  

#

route-policy vrrppolicy permit node 20  

if-match ip-prefix vrrp1  

apply cost 10  

3、引入路由

ospf 1 router-id 2.2.2.2  

import-route direct route-policy vrrppolicy

area 0.0.0.0  

 network 30.1.1.0 0.0.0.255 

R3配置：

1、选取网络

ip ip-prefix direct-to-ospf index 10 permit 10.1.1.0 24 greater-equal 24 less-eq

ual 24

ip ip-prefix direct-to-ospf1 index 10 permit 20.1.1.0 24 greater-equal 24 less-e

qual 24

2、策略，修改cost值

route-policy direct-ospf permit node 10  

if-match ip-prefix direct-to-ospf  

apply cost 20  

#

route-policy direct-ospf permit node 20  

if-match ip-prefix direct-to-ospf1  

apply cost 10  

3、引入路由

ospf 1 router-id 3.3.3.3  

import-route direct route-policy direct-ospf

area 0.0.0.0  

 network 40.1.1.0 0.0.0.255  

注意：通过修改cost参数，可以改变路由
