Procedure
Step 1 Import flows from the switch to the SPU.
# Configure the switch.
[Switch] sysname Switch
[Switch] vlan 10
[Switch-vlan10] quit
[Switch] interface gigabitethernet 1/0/4
[Switch-GigabitEthernet1/0/4] port link-type access
[Switch-GigabitEthernet1/0/4] port default vlan 10
[Switch-GigabitEthernet1/0/4] quit
[Switch] vlan 20
[Switch-vlan20] quit
[Switch] interface gigabitethernet 1/0/6
[Switch-GigabitEthernet1/0/6] port link-type access
[Switch-GigabitEthernet1/0/6] port default vlan 20
[Switch-GigabitEthernet1/0/6] quit
[Switch] interface eth-trunk 0
[Switch-Eth-Trunk0] port link-type trunk
[Switch-Eth-Trunk0] undo port trunk allow-pass vlan 1
[Switch-Eth-Trunk0] port trunk allow-pass vlan 10 20
[Switch-Eth-Trunk0] quit
[Switch] interface xgigabitethernet 2/0/0
[Switch-XGigabitEthernet2/0/0] eth-trunk 0
[Switch-XGigabitEthernet2/0/0] quit
[Switch] interface xgigabitethernet 2/0/1
[Switch-XGigabitEthernet2/0/1] eth-trunk 0
[Switch-XGigabitEthernet2/0/1] quit
# Configure the SPU on the switch.
[Quidway] sysname SPU
[SPU] interface eth-trunk 0
[SPU] interface xgigabitethernet 0/0/1
[SPU-XGigabitEthernet0/0/1] eth-trunk 0
[SPU] interface xgigabitethernet 0/0/2
[SPU-XGigabitEthernet0/0/2] eth-trunk 0
Step 2 Configure a VPN instance on the SPU.
[SPU] ip vpn-instance vpn-a
[SPU-vpn-instance-vpn-a] route-distinguisher 1:1
[SPU-vpn-instance-vpn-a] vpn-target 1:1
[SPU-vpn-instance-vpn-a] quit
[SPU] ip vpn-instance vpn-b
[SPU-vpn-instance-vpn-b] route-distinguisher 2:2
[SPU-vpn-instance-vpn-b] vpn-target 2:2
[SPU-vpn-instance-vpn-b] quit
Step 3 Create sub-interfaces on the SPU and bind the VPN instance to the sub-interfaces.
[SPU] interface eth-trunk 0.10
[SPU-Eth-Trunk0.10] control-vid 10 dot1q-termination
[SPU-Eth-Trunk0.10] dot1q termination vid 10
[SPU-Eth-Trunk0.10] ip binding vpn-instance vpn-a
[SPU-Eth-Trunk0.10] ip address 10.10.10.2 24
[SPU-Eth-Trunk0.10] arp broadcast enable
[SPU-Eth-Trunk0.10] quit
[SPU] interface eth-trunk 0.20
[SPU-Eth-Trunk0.20] control-vid 20 dot1q-termination
[SPU-Eth-Trunk0.20] dot1q termination vid 20
[SPU-Eth-Trunk0.20] ip binding vpn-instance vpn-b
[SPU-Eth-Trunk0.20] ip address 20.20.20.2 24
[SPU-Eth-Trunk0.20] arp broadcast enable
[SPU-Eth-Trunk0.20] quit
Step 4 Configure the static route on the SPU to allow the VPNs to communicate with each other.
