重发布实验

1.使用双点双向重发布

2.所有路由器进行最佳选路

3.存在备份路径，不得出现环路，和路由回馈

第一步：IP地址划分

设备	接口	地址
R1	GE0/0/0	12.1.1.1 24
	GE0/0/1	14.1.1.1 24
	Lookback0	1.1.1.1 24
R2	GE0/0/0	12.1.1.2 24
	S4/0/0	23.1.1.2 24
	Lookback0	2.2.2.2 24
R3	S4/0/0	23.1.1.3 24
	S4/0/1	34.1.1.3 24
	Lookback0	3.3.3.3 24
R4	GE0/0/0	14.1.1.4 24
	S4/0/0	34.1.1.4 24
	Lookback0	4.4.4.4 24

第二步：配IP

[r2-LoopBack0]ip address 2.2.2.2 24

[r2-GigabitEthernet0/0/0]ip address 12.1.1.2 24

[r2-Serial4/0/0]ip address 23.1.1.2 24

[r3-LoopBack0]ip address 3.3.3.3 24

[r3-Serial4/0/0]ip address 23.1.1.3 24

[r3-Serial4/0/1]ip address 34.1.1.3 24

[r4-GigabitEthernet0/0/0]ip address 14.1.1.4 24

[r4-LoopBack0]ip address 4.4.4.4 24

[r4-Serial4/0/0]ip address 34.1.1.4 24

第三步：宣告

[r1]rip 1

[r1-rip-1]ve        

[r1-rip-1]version 2

[r1-rip-1]ne        

[r1-rip-1]network 12.0.0.0

[r1-rip-1]ne        

[r1-rip-1]network 14.0.0.0

[r1-rip-1]ne        

[r1-rip-1]network 1.0.0.0

[r2]rip 1

[r2-rip-1]ve        

[r2-rip-1]verify-source

[r2-rip-1]version 2

[r2-rip-1]ne        

[r2-rip-1]network 12.0.0.0

[r2-rip-1]network 2.0.0.0

[r2-ospf-1-area-0.0.0.0]network 23.1.1.0 0.0.0.255

[r3]ospf 1

[r3-ospf-1]ar        

[r3-ospf-1]arp-ping         

[r3-ospf-1]area 0

[r3-ospf-1-area-0.0.0.0]ne        

[r3-ospf-1-area-0.0.0.0]network 3.3.3.0 0.0.0.255

[r3-ospf-1-area-0.0.0.0]ne        

[r3-ospf-1-area-0.0.0.0]network 23.1.1.0 0.0.0.255

[r3-ospf-1-area-0.0.0.0]network 34.1.1.0 0.0.0.255

[r4]rip 1

[r4-rip-1]ve        

[r4-rip-1]verify-source

[r4-rip-1]version 2

[r4-rip-1]ne        

[r4-rip-1]network 14.0.0.0

[r4]ospf 1

[r4-ospf-1]ar        

[r4-ospf-1]arp-ping

[r4-ospf-1]area 0

[r4-ospf-1-area-0.0.0.0]ne        

[r4-ospf-1-area-0.0.0.0]network 4.4.4.0 0.0.0.255

[r4-ospf-1-area-0.0.0.0]ne        

[r4-ospf-1-area-0.0.0.0]network 34.1.1.0 0.0.0.255

第三步：进行重发布

R2 和R4使用双点双向重发布
