VLANs
- On a router, if a physical interface is configured with many VLANs, then sub-interfaces have to be used. Additionally, the switchport port must be a trunk. An access port will not work, I tested this.
- Router(config)# interface g0/0.100
- Router(config-subif)# encapsulation dot1q 100
- Router(config-subif)# ip address 100.1.1.1 255.255.255.0
- —
- Switch(config)# interface g1/0/1
- Switch(config-if)# switchport trunk encapsulation dot1q
- Switch(config-if)# switchport mode trunk
- Switch(config-if)# switchport trunk allowed vlan 100
- A single vlan doesn't need to belong to a dot1q trunk to work.
- Router(config)# interface g0/1
- Router(config-if)# ip address 200.1.1.1 255.255.255.0
- —
- Switch(config)# interface g1/0/2
- Switch(config-if)# switchport mode access
- Switch(config-if)# switchport access vlan 200
