Configuration Example
Network Requirements
■ Create super VLAN 10 and sub VLANs VLAN 2, VLAN 3, VLAN 5.
■ Configure ports Ethernet2/0/1 and Ethernet2/0/2 to belong to VLAN 2,
Ethernet2/0/3 and Ethernet2/0/4 to belong to VLAN 3 and Ethernet2/0/5 and
Ethernet2/0/6 to belong to VLAN 5.
■ Configure Layer 3 connectivity between sub VLANs, and all sub VLANs use the
Layer 3 interface of the super VLAN (with the IP address being 10.110.1.1) as
the gateway to communicate with the outside.
