With the Layer 3 Switch set up in Pt.1\u00a0 it is time to look at some basic concepts of Layer 3 Switching. The Router on a Stick concept is technically not Layer 3 Switching since the Packet Forwarding (Routing) requires a Router.<\/p>\n

The basic concept of Router on a stick is implemented by creating subinterfaces on a single physical Router port. After the Switchport has been set to trunk mode (802.1q for you non-Cisco networkers), the subinterfaces can be assigned a VLAN by setting the trunk encapsulation to dot1q and a VLAN ID.<\/p>\n

This concept should work with any switch that supports VLANs. Another advantage of this concept is the fact that only one Router port is required in order to forward Layer 3 packets between the VLANs. The downsides however are a single point of failure and possible congestion (depending on the amount of VLANs and bandwidth utilization).<\/p>\n

Coming up next: Inter-VLAN Routing with Switched Virtual Interfaces (SVI) and Routed Ports which require Layer 3 switches.<\/p>\n
