- segment networks
- logical partition of a layer 2 network
- control broadcast domains
- has its own network
2
Q
types of vlans
A
- data vlan
- default vlan
- native vlan
- management vlan
3
Q
vlan trunks
A
- not associated with any vlans
- point to point link that carriers more than one vlan

tagged ethernet frames
A
- switches tag frames to identify which vlan they belong to
- adding vlan identification header to a frame
- used to properly transmit multiple vlan frames through a trunk link

- forwarding network traffic from one vlan to another using a router
6
Q
router on a stick inter vlan routing
A
- uses a different path to route between vlans
- uses one physical path
- router interface is configured as a trunk port so it can read vlan tags
- one logical sub interface per vlan
- vlan subinterface is networks default gateway
7
Q
multilayer switch inter vlan routing
A
- replaces dedicated router
- support dynamic routing and inter vlan routing
