1.基础配置? ??
R１——Ｒ５的环回为私有网段

[r5]ip route-static 0.0.0.0 0 56.0.0.2
R6为ISP，只能配置IP地址
[ISP-GigabitEthernet0/0/0]int g 0/0/1
[ISP-GigabitEthernet0/0/1] ip add 116.0.0.2 24
[ISP-GigabitEthernet0/0/1]int g 0/0/0

[ISP-GigabitEthernet4/0/0]ip add 36.0.0.2 24
[ISP-GigabitEthernet4/0/0]int g 4/0/1
[ISP-GigabitEthernet4/0/1]ip add 46.0.0.2 24
[ISP-GigabitEthernet4/0/1]int g 4/0/2
[ISP-GigabitEthernet4/0/2]ip add 56.0.0.2 24
２．MGRE配置
R1/2/3为星型拓扑结构，R1为中心点
[r1]int t 0/0/0
[r1-Tunnel0/0/]ip add 192.168.6.1?24??
[r1-Tunnel0/0/0]tunnel-protocol gre p2mp??
[r1-Tunnel0/0/0]source 16.0.0.1
[r1-Tunnel0/0/0]nhrp entry multicast dynamic?
[r1-Tunnel0/0/0]nhrp network-id 100? ??
?
[r2]int t 0/0/0
[r2-Tunnel0/0/0]ip add 192.168.6.2 24?
[r2-Tunnel0/0/0]tunnel-protocol gre p2mp?
[r2-Tunnel0/0/0]source g 0/0/0
[r2-Tunnel0/0/0]nhrp network-id 100??
[r2-Tunnel0/0/0]nhrp entry 192.168.6.1 16.0.0.1 register?
[r3]int t 0/0/0
[r3-Tunnel0/0/0]ip add 192.168.6.3 24??
[r3-Tunnel0/0/0]tunnel-protocol gre p2mp?
[r3-Tunnel0/0/0]source g 0/0/0
[r3-Tunnel0/0/0]nhrp network-id 100? ?
[r3-Tunnel0/0/0]nhrp entry 192.168.6.1 16.0.0.1 register?
?R1/4/5为全连MGRE结构
[r1]int t 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 116.0.0.1?
[r1-Tunnel0/0/1]nhrp entry multicast dynamic?
[r1-Tunnel0/0/1]nhrp network-id 110
[r1-Tunnel0/0/1]nhrp entry 192.168.7.2 46.0.0.1 register?
[r1-Tunnel0/0/1]nhrp entry 192.168.7.3 56.0.0.1 register
?
[r4]int t 0/0/0
[r4-Tunnel0/0/0]ip add 192.168.7.2 24?
[r4-Tunnel0/0/0]tunnel-protocol gre p2mp???

[r4-Tunnel0/0/0]nhrp entry 192.168.7.3 56.0.0.1 register
[r5]int t 0/0/0
[r5-Tunnel0/0/0]ip add 192.168.7.3 24
[r5-Tunnel0/0/0]tunnel-protocol gre p2mp?
[r5-Tunnel0/0/0]source 56.0.0.1
[r5-Tunnel0/0/0]nhrp network-id 110
[r5-Tunnel0/0/0]nhrp entry multicast dynamic?
[r5-Tunnel0/0/0]nhrp entry 192.168.7.1 116.0.0.1 register?
[r5-Tunnel0/0/0]nhrp entry 192.168.7.2 46.0.0.1 register
3.使用OSPF完成使所有私有网段可以互相通讯
[r1]ospf 1 router-id 1.1.1.1
[r1-ospf-1]a 0
[r1-ospf-1-area-0.0.0.0]network 192.168.1.0 0.0.0.255
[r1-ospf-1-area-0.0.0.0]network 192.168.6.0 0.0.0.255
