Super VLAN configuration examples
Example: Configuring a super VLAN
Network configuration
As shown in Figure 7:
• Twenty-FiveGigE 1/0/1 and Twenty-FiveGigE 1/0/2 are in VLAN 2.
• Twenty-FiveGigE 1/0/3 and Twenty-FiveGigE 1/0/4 are in VLAN 3.
• Twenty-FiveGigE 1/0/5 and Twenty-FiveGigE 1/0/6 are in VLAN 5.
To save IP addresses and enable sub-VLANs to be isolated at Layer 2 but interoperable at Layer 3,
perform the following tasks:
• Create a super VLAN and assign an IP address to its VLAN interface.
• Associate the super VLAN with VLANs 2, 3, and 5.
