[r1-Tunnel0/0/0]nhrp entry 192.168.6.2 4.0.0.1 register
[r1-Tunnel0/0/0]nhrp entry 192.168.6.3 5.0.0.1 register
R4
[Huawei]int Tunnel 0/0/0
[Huawei-Tunnel0/0/0]source GigabitEthernet 0/0/0
[Huawei-Tunnel0/0/0]nhrp network-id 100
[Huawei-Tunnel0/0/0]nhrp network-id 500
[Huawei-Tunnel0/0/0]nhrp entry 192.168.6.1 1.0.0.1 register
[Huawei-Tunnel0/0/0]nhrp entry 192.168.6.3 5.0.0.1 register
R5
[r5]int Tunnel 0/0/0
[r5-Tunnel0/0/0]source GigabitEthernet 0/0/0
[r5-Tunnel0/0/0]nhrp network-id 100
[r5-Tunnel0/0/0]nhrp network-id 400
[r5-Tunnel0/0/0]nhrp entry 192.168.6.1 1.0.0.1 register
[r5-Tunnel0/0/0]nhrp entry 192.168.6.2 4.0.0.1 register
对中心路由r1进行以下配置
[r1]interface Tunnel 0/0/1
[r1-Tunnel0/0/1]ip add 192.168.7.1 24
[r1-Tunnel0/0/1]tunnel-protocol gre p2mp
[r1-Tunnel0/0/1]source 6.0.0.1
[r1-Tunnel0/0/1]nhrp network-id 200
再对两个分支r2,r3进行配置
[r2]interface Tunnel 0/0/1
[r2-Tunnel0/0/1]ip add 192.168.7.2 24
[r2-Tunnel0/0/1]tunnel-protocol gre p2mp
[r2-Tunnel0/0/1]source GigabitEthernet 0/0/0
[r2-Tunnel0/0/1]nhrp network-id 200
[r2-Tunnel0/0/1]nhrp entry 192.168.7.1 6.0.0.1 register
[r3]int Tunnel 0/0/1
[r3-Tunnel0/0/1]ip add 192.168.7.3 24
[r3-Tunnel0/0/1]tunnel-protocol gre p2mp
[r3-Tunnel0/0/1]source GigabitEthernet 0/0/0
[r3-Tunnel0/0/1]nhrp network-id 200
[r3-Tunnel0/0/1]nhrp entry 192.168.7.1 6.0.0.1 register
4、有私有网段可以互相通讯,私有网段使用OSPF完成。
[r1]ospf 1 router-id 2.2.2.2
[r1-ospf-1]area 0
[r1-ospf-1-area-0.0.0.0]network 192.168.1.1 0.0.0.0
[r1-ospf-1-area-0.0.0.0]network 192.168.1.1 0.0.0.0
[r1-ospf-1-area-0.0.0.0]network 192.168.1.1 0.0.0.0
[r2]ospf 1 router-id 2.2.2.2
[r2-ospf-1]area 0
[r2-ospf-1-area-0.0.0.0]network 192.168.2.1 0.0.0.0
[r2-ospf-1-area-0.0.0.0]network 192.168.7.0 0.0.0.255
[r3]ospf 1 router-id 3.3.3.3
[r3-ospf-1]area 0
[r3-ospf-1-area-0.0.0.0]network 192.168.3.1 0.0.0.0
[r3-ospf-1-area-0.0.0.0]network 192.168.7.0 0.0.0.255
[r4]ospf 1 router-id 4.4.4.4
[r4-ospf-1]area 0
[r4-ospf-1-area-0.0.0.0]network 192.168.4.1 0.0.0.0
[r4-ospf-1-area-0.0.0.0]network 4.0.0.0 0.0.0.255
[r5]ospf 1 router-id 5.5.5.5
[r5-ospf-1]area 0
[r5-ospf-1-area-0.0.0.0]network 192.168.5.1 0.0.0.0
[r5-ospf-1-area-0.0.0.0]network 5.0.0.0 0.0.0.255
将R1、R4、R5的接口类型改为Broadcast类型
[r1-Tunnel0/0/0]ospf network-type broadcast
[r4-Tunnel0/0/0]ospf network-type broadcast
[r5-Tunnel0/0/0]ospf network-type broadcast
三、修改R2,R3的优先级,把R2,R3的优先级改为0,让他们放弃选举
[r2]int t0/0/1
[r2-Tunnel0/0/1]ospf dr-priority 0
[r3-Tunnel0/0/1]ospf dr-priority 0
达到全网可通
