Ambiguous Dot1q termination configuration example
Network requirements
As shown in Figure 20, configure ambiguous Dot1q termination, so that hosts in different VLANs can communicate with the server group.

Configuration procedure
In this example, L2 switch B uses the factory configuration.
Configure Host A, Host B, and Host C:
# Assign 1.1.1.1/24, 1.1.1.2/24, and 1.1.1.3/24 to Host A, Host B, and Host C, respectively. (Details not shown.)
# Specify 1.1.1.11/24 as the gateway IP address for the hosts. (Details not shown.)
Configure Layer 2 Switch A:
# Create VLAN 11.
<L2_SwitchA> system-view [L2_SwitchA] vlan 11
# Assign GigabitEthernet 2/1/1 to VLAN 11.
[L2_SwitchA-vlan11] port gigabitethernet 2/1/1 [L2_SwitchA-vlan11] quit
# Create VLAN 12.
[L2_SwitchA] vlan 12
# Assign GigabitEthernet 2/1/2 to VLAN 12.
[L2_SwitchA-vlan12] port gigabitethernet 2/1/2 [L2_SwitchA-vlan12] quit
# Create VLAN 13.
[L2_SwitchA] vlan 13
# Assign GigabitEthernet 2/1/3 to VLAN 13.
[L2_SwitchA-vlan13] port gigabitethernet 2/1/3 [L2_SwitchA-vlan13] quit
# Configure GigabitEthernet 2/1/7 as a trunk port, and assign the port to VLANs 11 through 13.
[L2_SwitchA] interface gigabitethernet 2/1/7 [L2_SwitchA-GigabitEthernet2/1/7] port link-type trunk [L2_SwitchA-GigabitEthernet2/1/7] port trunk permit vlan 11 to 13
Configure the device:
# Create Ethernet subinterface GigabitEthernet 2/1/1.10, and assign an IP address to the subinterface.
<Device> system-view [Device] interface gigabitethernet 2/1/1.10 [Device-GigabitEthernet2/1/1.10] ip address 1.1.1.11 255.255.255.0
# Enable Dot1q termination on GigabitEthernet 2/1/1.10 to terminate VLAN-tagged packets whose Layer 1 VLAN IDs are 11, 12, or 13.
[Device-GigabitEthernet2/1/1.10] vlan-type dot1q vid 11 to 13
# Enable GigabitEthernet 2/1/1.10 to transmit broadcasts and multicasts.
[Device-GigabitEthernet2/1/1.10] vlan-termination broadcast enable [Device-GigabitEthernet2/1/1.10] quit
# Assign an IP address to GigabitEthernet 2/1/2.
[Device] interface gigabitethernet 2/1/2 [Device-GigabitEthernet2/1/2] ip address 1.1.2.11 255.255.255.0
Configure the server group:
# Assign each device in the server group an IP address on the network segment 1.1.2.0/24. (Details not shown.)
# Specify 1.1.2.11/24 as the gateway IP address for the server group. (Details not shown.)
Verifying the configuration
# Verify that Host A, Host B, and Host C can ping the device in the server group. (Details not shown.)
