Inter-VLAN Layer 2 forwarding configuration
example
Network requirements
As shown in Figure 44, traffic between GigabitEthernet 3/0/1 and GigabitEthernet 3/0/2 is filtered by
a firewall card, and inter-VLAN Layer 2 forwarding needs to be configured.
• Configure the operating mode of GigabitEthernet 3/0/1 and GigabitEthernet 3/0/2 of the switch
as access. Assign them to VLAN 102 and VLAN 103 respectively.
• Ten-GigabitEthernet 2/0/1 of the switch connects to Ten-GigabitEthernet 0/0 of the firewall card.
Configure the operating mode of the two interfaces as Layer 2 and the link type as trunk.
• Create two subinterfaces Ten-GigabitEthernet 0/0.102 and Ten-GigabitEthernet 0/0.103 for
Ten-GigabitEthernet 0/0. Configure their operating mode as Layer 2 and the link type as access.
Assign them to VLAN 1000.
