第一步：配IP

[R1-GigabitEthernet0/0/0]ip address 12.0.0.1 24

[R1-GigabitEthernet0/0/1]ip address 21.0.0.1 24

[R1-LoopBack0]ip address 192.168.1.1 24

[ISP-GigabitEthernet0/0/0]ip address 12.0.0.2 24

[ISP-GigabitEthernet0/0/1]ip address 21.0.0.2 24

[ISP-GigabitEthernet0/0/2]ip address 23.0.0.2 24

[R3-Tunnel0/0/0]shutdown
[R3-Tunnel0/0/0]source 23.0.0.1
[R3-Tunnel0/0/0]nhrp network-id 100

[R3-Tunnel0/0/0]nhrp entry 192.168.10.4 24.0.0.1 register

[R3-Tunnel0/0/0]nhrp entry multicast dynamic

[R3-Tunnel0/0/0]ospf network-type broadcast

[R4-Tunnel0/0/0]shutdown
[R4-Tunnel0/0/0]source 24.0.0.1
[R4-Tunnel0/0/0]nhrp network-id 100

[R4-Tunnel0/0/0]nhrp entry multicast dynamic

[R4-Tunnel0/0/0]ospf network-type broadcast

[R4- Tunnel0/0/0]nhrp entry 192.168.10.1 21.0.0.1 register

[R1]int t0/0/1
[R1-Tunnel0/0/1]ip address 192.168.100.1 24
[R1-Tunnel0/0/1]tunnel-protocol gre p2mp
[R1-Tunnel0/0/1]shutdown
[R1-Tunnel0/0/1]source 12.0.0.1
