關於如何配置路由器BGP問題很大，在這裡只是舉個小例子加以說明了，王海軍老師為你解答！

1、問題：

R1 R2 R3 建立rip 協議,同時屬於BGP 1 。R4 是預設路由，為BGP22、拓撲圖： 3、配置： R1 配置：

interface FastEthernet0/0 ip address 192.168.1.1 255.255.255.0

router rip network 192.168.1.0

router bgp 1 no synchronization bgp log-neighbor-changes neighbor 192.168.1.2 remote-as 1 neighbor 192.168.2.2 remote-as 1 no auto-summary

R2 配置：

interface FastEthernet0/0 ip address 192.168.1.2 255.255.255.0

interface FastEthernet1/0 ip address 192.168.2.1 255.255.255.0router rip network 192.168.1.0 network 192.168.2.0router bgp 1 no synchronization bgp log-neighbor-changes neighbor 192.168.1.1 remote-as 1 neighbor 192.168.2.2 remote-as 1 no auto-summary

R3配置：

interface FastEthernet0/0 ip address 192.168.3.1 255.255.255.0interface FastEthernet1/0 ip address 192.168.2.2 255.255.255.0

router rip network 192.168.2.0

router bgp 1 no synchronization bgp log-neighbor-changes network 192.168.3.0 neighbor 192.168.1.1 remote-as 1 neighbor 192.168.2.1 remote-as 1 neighbor 192.168.3.2 remote-as 2 no auto-summary

R4配置：

interface FastEthernet0/0 ip address 192.168.3.2 255.255.255.0

router bgp 2 no synchronization bgp log-neighbor-changes neighbor 192.168.3.1 remote-as 1 no auto-summary

ip route 0.0.0.0 0.0.0.0 192.168.3.1

=============================================

R1檢視路由表：

路由表學到，實驗成功！
