<Huawei> system-view
[Huawei] sysname SwitchB
[SwitchB] vlan 10
[SwitchB-vlan10] port gigabitethernet 1/0/0
[SwitchB-vlan10] quit
[SwitchB] interface gigabitethernet 1/0/1
[SwitchB-GigabitEthernet1/0/1] port trunk allow-pass vlan 10
[SwitchB-GigabitEthernet1/0/1] quit
# Configure SwitchC.
<Huawei> system-view
[Huawei] sysname SwitchC
[SwitchC] vlan 20
[SwitchC-vlan20] port gigabitethernet 1/0/0
[SwitchC-vlan20] quit
[SwitchC] interface gigabitethernet 1/0/1
[SwitchC-GigabitEthernet1/0/1] port trunk allow-pass vlan 20
[SwitchC-GigabitEthernet1/0/1] quit
Step 4 Configure the QinQ function on SwitchA to ensure that packets sent from SwitchA to RouterA
and RouterB carry two tags.
Step 5 Verify the configuration.
# The VRRP backup group can function as the gateway.
Run the display vrrp command on RouterA and RouterB to verify that RouterA functions as
the master and RouterB functions as the backup.
[RouterA] display vrrp
GigabitEthernet2/0/0.1 | Virtual Router 1
GigabitEthernet2/0/0.2 | Virtual Router 2
[RouterB] display vrrp
