Inter-VLAN Layer 3 forwarding configuration
example
Network requirements
As shown in the Figure 177, traffic between GigabitEthernet 3/0/1 and GigabitEthernet 3/0/2 is
filtered by a firewall card, and inter-VLAN Layer 3 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 link type of the two interfaces as trunk.
• Configure the operating mode of ten-GigabitEthernet 0/0 as Layer 2. Create two VLAN interfaces
VLAN-interface 102 and VLAN-interface 103.
• Assign IP address 102.0.0.3/24 to VLAN-interface 102 and 103.0.0.3/24 to VLAN-interface 103.
• Add the firewall card's ten-GigabitEthernet interface and the VLAN interfaces to security zones
Trust and Untrust.
