Inter-VLAN Layer 2 forwarding configuration example
Network requirements
As shown in Figure 35 , traffic between GigabitEthernet 3/0/1 and GigabitEthernet 3/0/2 is filtered by
a SecBlade card, and inter-VLAN Layer 2 forwarding needs to be configured.
• Ten-GigabitEthernet 2/0/1 of the device connects to Ten-GigabitEthernet 0/0 of the SecBlade
card. Configure the link type of the two interfaces as trunk.
• Configure the operating mode of Ten-GigabitEthernet 2/0/1 as Layer 2. Assign the port to VLAN
102 and VLAN 103. Set the default VLAN of the port as VLAN 100.
• Configure the operating mode of GigabitEthernet 3/0/1 and GigabitEthernet 3/0/2 of the device
as access. Assign them to VLAN 102 and VLAN 103 respectively.
• Configure the operating mode of Ten-GigabitEthernet 0/0 as Layer 2. Assign the port to VLAN 102,
VLAN 103, and VLAN 1000 (the VLAN where the SecBlade card resides).
• 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.
