HCIP实验（04）

拓扑设计和IP地址规划

1.配置路由器接口IP地址和环回

[r1]int LoopBack 0
[r1-LoopBack0]ip add 192.168.1.1 24
[r1]int g0/0/0
[r1-GigabitEthernet0/0/0]ip add 16.1.1.1 24
[r1]int g0/0/2
[r1-GigabitEthernet0/0/2]ip add 61.1.1.1 24
[r2]int LoopBack 0
[r2-LoopBack0]ip add 192.168.2.1 24
[r2]int g0/0/0
[r2-GigabitEthernet0/0/0]ip add 26.1.1.1 24
[r3]int LoopBack 0
[r3-LoopBack0]ip add 192.168.3.1 24
[r3]int g0/0/0
[r3-GigabitEthernet0/0/0]ip add 36.1.1.1 24
[r4]int LoopBack 0
[r4-LoopBack0]ip add 192.168.4.1 24
[r4]int g0/0/0
[r4-GigabitEthernet0/0/0]ip add 46.1.1.1 24
[r5]int LoopBack 0
[r5]int lo0
[r5-LoopBack0]ip add 192.168.5.1 24
[r5]int g0/0/0
[r5-GigabitEthernet0/0/0]ip add 56.1.1.1 24
[r6]int LoopBack 0
[r6-LoopBack0]ip add 6.6.6.6 24
[r6]int g0/0/0
[r6-GigabitEthernet0/0/0]ip add 16.1.1.2 24
[r6]int g4/0/1
[r6-GigabitEthernet4/0/1]ip add 61.1.1.2 24
[r6]int g0/0/1
[r6-GigabitEthernet0/0/1]ip add 26.1.1.2 24
[r6]int g0/0/2
[r6-GigabitEthernet0/0/2]ip add 36.1.1.2 24
[r6]int g2/0/0
[r6-GigabitEthernet2/0/0]ip add 46.1.1.2 24
[r6]int g2/0/1 
[r6-GigabitEthernet2/0/1]ip add 56.1.1.2 24

2.配置缺省路由

[r1]ip route-static 0.0.0.0 0 16.1.1.2
[r1]ip route-static 0.0.0.0 0 61.1.1.2
[r2]ip route-static 0.0.0.0 0 26.1.1.2
[r3]ip route-static 0.0.0.0 0 36.1.1.2
[r4]ip route-static 0.0.0.0 0 46.1.1.2
[r5]ip route-static 0.0.0.0 0 56.1.1.2

测试

3.构建MGRE环境

[r1]int t0/0/0
[r1-Tunnel0/0/0]ip add 10.1.1.1 24
[r1-Tunnel0/0/0]tunnel-protocol gre p2mp 
[r1-Tunnel0/0/0]source 16.1.1.1
[r1-Tunnel0/0/0]nhrp entry multicast dynamic 
[r1-Tunnel0/0/0]nhrp network-id 100
[r2]int t0/0/0
[r2-Tunnel0/0/0]ip add 10.1.1.2 24
[r2-Tunnel0/0/0]tunnel-protocol gre p2mp 
[r2-Tunnel0/0/0]source g0/0/0
[r2-Tunnel0/0/0]nhrp entry 10.1.1.1 16.1.1.1 register 
[r2-Tunnel0/0/0]nhrp network-id 100
[r3]int t0/0/0
[r3-Tunnel0/0/0]ip add 10.1.1.3 24
[r3-Tunnel0/0/0]tunnel-protocol gre p2mp 
[r3-Tunnel0/0/0]source g0/0/0
[r3-Tunnel0/0/0]nhrp entry 10.1.1.1 16.1.1.1 register 
[r3-Tunnel0/0/0]nhrp network-id 100

[r1]int t0/0/1
[r1-Tunnel0/0/1]ip add 10.1.2.1 24
[r1-Tunnel0/0/1]tunnel-protocol gre p2mp 
[r1-Tunnel0/0/1]source 61.1.1.1
[r1-Tunnel0/0/1]nhrp entry multicast dynamic 
[r1-Tunnel0/0/1]nhrp network-id 101
[r4]int t0/0/0
[r4-Tunnel0/0/0]ip add 10.1.2.2 24
[r4-Tunnel0/0/0]tunnel-protocol gre p2mp 
[r4-Tunnel0/0/0]source 46.1.1.1
[r4-Tunnel0/0/0]nhrp entry 10.1.2.1 61.1.1.1 register 
[r4-Tunnel0/0/0]nhrp entry 10.1.2.3 56.1.1.1 register 
[r4-Tunnel0/0/0]nhrp network-id 101
[r5]int t0/0/0
[r5-Tunnel0/0/0]ip add 10.1.2.3 24
[r5-Tunnel0/0/0]tunnel-protocol gre p2mp 
[r5-Tunnel0/0/0]source 56.1.1.1
[r5-Tunnel0/0/0]nhrp entry 10.1.2.1 61.1.1.1 register 
[r5-Tunnel0/0/0]nhrp entry 10.1.2.2 46.1.1.1 register
[r5-Tunnel0/0/0]nhrp network-id 101
（打开R5的t0/0/0的伟光播）
