into a single logical channel that can be configured for Layer 3 processing
■ 5-4: WAN Interfaces: Describes how to configure Layer 3 WAN interfaces installed
in Catalyst 6500 switches
5-5: Layer 3 Virtual Interfaces: Explains how to configure a logical VLAN or BVI
■
to perform Layer 3 processing for members of a VLAN or bridge group
5-6: Routing Tables: Explains the basic process for populating and viewing the Layer
■
3 routing tables
5-1: Layer 3 Switching
Layer 3 switching is the movement of data between devices using tables or pathways
■
containing Layer 3 network addressing.
To perform Layer 3 switching, the device must have a Layer 3 switching processor
■
that can be a separate module or card.
A Layer 3 switching processor uses Layer 3 IOS to configure the Layer 3 switching
■
components.
■ To allow Layer 3 switching, the switch must have the routing function enabled for a
given protocol.
