BGP实验

Posted 2021-06-24 ‘朱砂痣’、

要求：

操作思路：先配好两台路由的接口地址以及回环地址，然后RIP一下自己所在的网段

之后的话就是BGP创建

rip 

v 2

network 

undo summary

router id

bgp 100

peer 对方的ip（这里是对方的回环地址） as-number 

peer 对方的ip（这里是对方的回环地址）connect-interface LoopBack 0

network  ip   子网（自己路由器的信息）

话不多说，直接上手

R1配置：

[R1]int g0/0/0
[R1-GigabitEthernet0/0/0]ip add 12.0.0.1 30
[R1-GigabitEthernet0/0/0]un sh
Info: Interface GigabitEthernet0/0/0 is not shutdown.

[R1-GigabitEthernet0/0/0]int loo 0//配置3个回环口ip/子网
[R1-LoopBack0]ip add 1.1.1.1 32
[R1-LoopBack0]q
[R1]int loo 1
[R1-LoopBack1]ip add 3.0.0.1 24
[R1-LoopBack1]int loo 2
[R1-LoopBack2]ip add 4.0.0.1 24
[R1-LoopBack2]q
