Explanation:
To transport packets between VLANs, you must use a Layer 3 device. Traditionally, this has
been a
router’s function. The router must have a physical or logical connection to each VLAN so that
it can
forward packets between them. This is known as interVLAN routing.
InterVLAN routing can be performed by an external router that connects to each of the
VLANs on
a switch. Separate physical connections can be used, or the router can access each of the
VLANs
through a single trunk link.
