BGP初步配置实验 _初步

金鞍玉勒寻芳客，未信我庐别有春。这篇文章主要讲述BGP初步配置实验相关的知识，希望能为你提供帮助。
实验要求：
结合其他路由协议，完成BGP初步配置，实现全网互通。

实验环境：

实验配置：
基本配置：IOU1:

config terminal
int e0/0
ip address 12.12.12.1 255.255.255.0
no shutdown
int loop 0
ip address 1.1.1.1 255.255.255.255
no shutdown
exit

IOU2:

config terminal
int e0/0
ip address 12.12.12.2 255.255.255.0
no shutdown
int e0/1
ip address 23.23.23.2 255.255.255.0
no shutdown
int loop 0
ip address 2.2.2.2 255.255.255.0
no shutdown
exit

IOU3:

config terminal
int e0/0
ip address 23.23.23.3 255.255.255.0
no shutdown
int e0/1
ip address 34.34.34.3 255.255.255.0
no shutdown
int loop 0
ip address 3.3.3.3 255.255.255.255
no shutdown
exit

IOU4:

config terminal
int e0/0
ip address 34.34.34.4 255.255.255.0
no shutdown
int loop 0
ip address 4.4.4.4 255.255.255.255
no shutdown
exit

路由配置：IOU1:

router bgp 100
bgp router-id 1.1.1.1
no synchronization
neighbor 2.2.2.2 remote-as 100
neighbor 2.2.2.2 update-source loopback 0

network 1.1.1.1 mask 255.255.255.255
neighbor 3.3.3.3 remote-as 100
neighbor 3.3.3.3 update-source loopback 0
exit
router ospf 1
network 1.1.1.1 0.0.0.0 area 0
network 12.12.12.0 0.0.0.255 area 0
exit

IOU2:

router bgp 100

neighbor 4.4.4.4 ebgp-multihop 10
exit
ip route 4.4.4.0 255.255.255.0 34.34.34.4
