Network requirements
As shown in
Primary VLAN 10 on Device B is associated with secondary VLANs 2 and 3. The IP address of
•
VLAN-interface 10 is 192.168.1.1/24.
The uplink port Ten-GigabitEthernet 1/1/5 is in VLAN 10. The ports Ten-GigabitEthernet 1/1/6
•
and Ten-GigabitEthernet 1/1/7 are in VLAN 2 and VLAN 3, respectively.
• Secondary VLANs are isolated at Layer 2 but interoperable at Layer 3.
