Procedure
Step 1 Configure the interface connected to Switch A.
# Create and configure sub-interface GE 1/0/1.1.
<Quidway> system-view
[Quidway] interface gigabitethernet 1/0/1.1
[Quidway-GigabitEthernet1/0/1.1] control-vid 100 dot1q-termination rt-protocol
[Quidway-GigabitEthernet1/0/1.1] dot1q termination vid 10
[Quidway-GigabitEthernet1/0/1.1] ip address 10.10.10.1 24
[Quidway-GigabitEthernet1/0/1.1] arp broadcast enable
[Quidway-GigabitEthernet1/0/1.1] quit
Step 2 Configure the interface connected to Switch B.
# Create and configure sub-interface GE 1/0/2.1.
[Quidway] interface gigabitethernet 1/0/2.1
[Quidway-GigabitEthernet1/0/2.1] control-vid 200 dot1q-termination rt-protocol
[Quidway-GigabitEthernet1/0/2.1] dot1q termination vid 20
[Quidway-GigabitEthernet1/0/2.1] ip address 20.20.20.1 24
[Quidway-GigabitEthernet1/0/2.1] arp broadcast enable
[Quidway-GigabitEthernet1/0/2.1] quit
Step 3 Verify the configuration.
On PC 1 in VLAN 10, set default gateway address to the IP address of GE 1/0/1.1, that is,
10.10.10.1/24.
On PC 2 in VLAN 20, set default gateway address to the IP address of GE 1/0/2.1, that is,
20.20.20.1/24.
After the configuration, PC 1 in VLAN 10 and PC 2 in VLAN 20 can communicate with each
other.
