實驗步驟

一、配置路由器R1

#
interface GigabitEthernet0/0/0
 ip address 12.0.0.1 255.255.255.252 
#
interface GigabitEthernet0/0/1
 ip address 15.0.0.1 255.255.255.252 
#
interface LoopBack0
 ip address 1.1.1.1 255.255.255.255 
#
bgp 100
 router-id 1.1.1.1
 peer 2.2.2.2 as-number 100 
 peer 2.2.2.2 connect-interface LoopBack0
 peer 5.5.5.5 as-number 100 
 peer 5.5.5.5 connect-interface LoopBack0
#
ospf 1 router-id 1.1.1.1 
 area 0.0.0.0 
 network 12.0.0.0 0.0.0.3 
 network 15.0.0.0 0.0.0.3 
 network 1.1.1.1 0.0.0.0 
 area 0.0.0.1 

二、配置路由器R2

 peer 3.3.3.3 ebgp-max-hop 2 
 peer 3.3.3.3 connect-interface LoopBack0
 peer 5.5.5.5 as-number 100 
 peer 5.5.5.5 connect-interface LoopBack0
#
 ipv4-family unicast
 undo synchronization
 peer 1.1.1.1 enable

 network 12.0.0.0 0.0.0.3 
 network 23.0.0.0 0.0.0.3 
 network 2.2.2.2 0.0.0.0 
#
rip 1
 version 2
 network 23.0.0.0
 network 2.0.0.0

三、配置路由器R3

#
interface GigabitEthernet0/0/1
 ip address 23.0.0.2 255.255.255.252 
#
interface LoopBack0
 ip address 3.3.3.3 255.255.255.255 
#
bgp 200
 router-id 3.3.3.3
 peer 2.2.2.2 as-number 100 
 peer 2.2.2.2 ebgp-max-hop 2 
 peer 2.2.2.2 connect-interface LoopBack0
#
rip 1
 version 2
 network 3.0.0.0
 network 23.0.0.0

四、配置路由器R5

#
interface GigabitEthernet0/0/1
 ip address 15.0.0.2 255.255.255.252 
#
interface LoopBack0
 ip address 5.5.5.5 255.255.255.255 
#
interface LoopBack1
 ip address 202.0.0.1 255.255.255.0 
#
interface LoopBack2
 ip address 202.0.1.1 255.255.255.0 
#
bgp 100
 router-id 5.5.5.5
 peer 1.1.1.1 as-number 100 
 peer 1.1.1.1 connect-interface LoopBack0
 peer 2.2.2.2 as-number 100 
 peer 2.2.2.2 connect-interface LoopBack0
#
ospf 1 router-id 5.5.5.5 
 area 0.0.0.0 
 network 5.5.5.5 0.0.0.0 
 network 15.0.0.0 0.0.0.3 
 network 202.0.0.0 0.0.0.255
