InterVLAN routing using Layer 3 switch
Multilayer switches can forward frames based on MAC address information and can also forward IP packets based on IP destination. That is why they are also referred to as Layer 3 switches.
Forwarding Data Between VLANs
This lesson discusses the most basic method of forwarding data between VLANs using a router with multiple Interfaces. Each VLAN connects to a separate physical interface on the router. This method is older and not common today.
VLAN Trunking
This lesson discusses VLAN trunking - a technology that switches use to carry traffic for multiple VLANs over a single physical link called a trunk link. It is a fundamental topic of the CCNA exam and the networking field in general.
VLAN Concept
This lesson discusses arguably the most important topic in the networking field - Virtual LANs (VLANs). It is a simple yet very powerful concept that changed the network industry and is nowadays used in EVERY network.
