41、BGP配置实验之MD5认证

1、实验拓扑

2、基础配置

R1配置

interface Serial0/0

 ip address 12.1.1.1 255.255.255.0

router bgp 1

 no synchronization

 bgp router-id 1.1.1.1

 neighbor 12.1.1.2 remote-as 2

R2配置

interface Serial0/0

 ip address 12.1.1.2 255.255.255.0

router bgp 2

 no synchronization

 bgp router-id 2.2.2.2

 neighbor 12.1.1.1 remote-as 1

 no auto-summary

3、配置MD5认证

配置MD5认证前

在R1上单边配置MD5认证

R1(config)#router bgp 1

R1(config-router)#neighbor 12.1.1.2 password cisco

在R2上也配置MD5认证

R2(config)#router bgp 2

R2(config-router)#neighbor 12.1.1.1 password cisco
