 实验拓扑：

 实验过程：

1、IP地址配置

2、对r2\r3\r4oSPF配置

R2:
	ospf 1 router-id 2.2.2.2
		area 0
			network 2.2.2.2 0.0.0.0
			network 23.1.1.10.0.0.0

R3:
	ospf 1 router-id 3.3.3.3
		area 0
			network 3.3.3.3 0.0.0.0
			network 23.1.1.2 0.0.0.0
			network 34.1.1.1 0.0.0.0

R4:
	ospf 1 router-id 4.4.4.4
		area 0
			network 4.4.4.4 0.0.0.0
			network 34.1.1.2 0.0.0.0

3、BGP配置

R1:
	bgp 1
		router-id 1.1.1.1
		peer 12.1.1.2 as-number 2
		
R2:
	bgp 2
		router-id 2.2.2.2
		peer 12.1.1.1 as-number 1
		peer 3.3.3.3 as-number 2
		peer 3.3.3.3 connect-interface LoopBack 0
		
R3:
	bgp 2
		router-id 3.3.3.3
		peer 2.2.2.2 as-number 2
		peer 2.2.2.2 connect-interface LoopBack 0
		peer 4.4.4.4 as-number 2
		peer 4.4.4.4 connect-interface LoopBack 0

R4:
	bgp 2
		router-id 4.4.4.4
		peer 3.3.3.3 as-number 2
		peer 3.3.3.3 connect-interface LoopBack 0
		peer 5.5.5.5 as-number 3
		peer 5.5.5.5 connect-interface LoopBack 0
		peer 5.5.5.5 ebgp-max-hop 2

R5:
	bgp 3
		router-id 5.5.5.5
		peer 4.4.4.4 as-number 2
		peer 4.4.4.4 connect-interface LoopBack 0
		peer 4.4.4.4 ebgp-max-hop 2

4、r4\r5  EBGP配置

R4:
	ip route-static 5.5.5.5 24 45.1.1.2
	ip route-static 5.5.5.5 24 54.1.1.2
	
R5:
	ip route-static 4.4.4.4 24 45.1.1.1
	ip route-static 4.4.4.4 24 54.1.1.1

5、BGP宣告

R1：
	bgp 1
		network 1.1.1.1 24

R5：
	bgp 3
		network 5.5.5.5 24

修改下一跳

R2：
	bgp 2
		peer 3.3.3.3 next-hop-local

R4：
	bgp 2
		peer 3.3.3.3 next-hop-local

R2与R4建邻

R2:
	bgp 2 
		peer 4.4.4.4 as-number 2
		peer 4.4.4.4 connect-interface LoopBack 0
		peer 4.4.4.4 next-hop-local

R4:
	bgp 2 
		peer 2.2.2.2 as-number 2
		peer 2.2.2.2 connect-interface LoopBack 0
		peer 2.2.2.2 next-hop-local
