[R1-GigabitEthernet0/0/2]ip address 192.168.1.254 24

8）R1的G0/0/1端口绑定

[R1]interface GigabitEthernet 0/0/1
[R1-GigabitEthernet0/0/1]ip binding vpn-instance 2
Info: All IPv4 related configurations on this interface are removed!
Info: All IPv6 related configurations on this interface are removed!
[R1-GigabitEthernet0/0/1]ip address 192.168.2.254 24

9）R1的G1/0/0端口绑定

[R1]interface GigabitEthernet 1/0/0
[R1-GigabitEthernet1/0/0]ip binding vpn-instance 2
Info: All IPv4 related configurations on this interface are removed!
Info: All IPv6 related configurations on this interface are removed!
[R1-GigabitEthernet1/0/0]ip address 192.168.1.254 24

10）R1配置OSFP

[R1]ospf 1 router-id 1.1.1.1 vpn-instance 1
[R1-ospf-1]area 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 192.168.2.0 0.0.0.255

[R1]ospf 2 router-id 1.1.1.1 vpn-instance 2     
[R1-ospf-2]area 0
