HCIP练习04（重发布）

1.配置IP地址和环回

[r1]int lo0
[r1-LoopBack0]ip add 1.1.1.1 24
[r1]int g0/0/0
[r1-GigabitEthernet0/0/0]ip add 12.1.1.1 24
[r1]int g0/0/1
[r1-GigabitEthernet0/0/1]ip add 14.1.1.1 24
[r2]int lo0 
[r2-LoopBack0]ip add 2.2.2.2 24
[r2]int g0/0/0
[r2-GigabitEthernet0/0/0]ip add 12.1.1.2 24
[r2]int g0/0/1
[r2-GigabitEthernet0/0/1]ip add 23.1.1.1 24
[r3]int lo0
[r3-LoopBack0]ip add 3.3.3.3 24
[r3]int g0/0/0
[r3-GigabitEthernet0/0/0]ip add 23.1.1.2 24
[r3]int g0/0/1
[r3-GigabitEthernet0/0/1]ip add 34.1.1.1 24
[r4]int lo0
[r4-LoopBack0]ip add 4.4.4.4 24
[r4]int g0/0/0
[r4-GigabitEthernet0/0/0]ip add 34.1.1.2 24
[r4]int g0/0/1
[r4-GigabitEthernet0/0/1]ip add 14.1.1.2 24

（测试）

2.进行RIP和OSPF宣告

[r1]rip 1
[r1-rip-1]ver 2
[r1-rip-1]network 1.0.0.0
[r1-rip-1]network 12.0.0.0
[r1-rip-1]network 14.0.0.0
[r2]rip 1
[r2-rip-1]ver 2
[r2-rip-1]network 12.0.0.0
[r2-rip-1]network 2.0.0.0
[r2]ospf 1 router-id 2.2.2.2
[r2-ospf-1]area 0
[r2-ospf-1-area-0.0.0.0]network 23.1.1.1 0.0.0.0
[r3]ospf 1 router-id 3.3.3.3
[r3-ospf-1]area 0
[r3-ospf-1-area-0.0.0.0]network 23.1.1.2 0.0.0.0
[r3-ospf-1-area-0.0.0.0]network 3.3.3.3 0.0.0.0
[r3-ospf-1-area-0.0.0.0]network 34.1.1.1 0.0.0.0
[r4]rip 1
[r4-rip-1]ver 2
[r4-rip-1]network 14.0.0.0
[r4]ospf 1 router-id 4.4.4.4
[r4-ospf-1]area 0
[r4-ospf-1-area-0.0.0.0]network 34.1.1.2 0.0.0.0
[r4-ospf-1-area-0.0.0.0]network 4.4.4.4 0.0.0.0

3.开启多点双向重发布

[r2]ospf 1 
[r2-ospf-1]import-route rip
[r2]rip 1
[r2-rip-1]import-route ospf
[r4]ospf 1 
[r4-ospf-1]import-route rip
[r4]rip 1
[r4-rip-1]import-route ospf

（查看）

4.优化

（1）两边只能学到掩码为32位的路由

[r4]int lo0
[r4-LoopBack0]ip add 4.4.4.4 32

（2）两边只能学到掩码为24位的路由

[r4]int lo0
[r4-LoopBack0]ospf network-type broadcast 
[r4-LoopBack0]ip add 4.4.4.4 24
