Chapter 4. Implementing Inter-VLAN Routing

This chapter covers the following topics:

• Describing Inter-VLAN Routing

• Configuring Inter-VLAN Routing

• Implementing Dynamic Host Configuration Protocol in a Multilayer Switched Environment

• Deploying CEF-Based Multilayer Switching

Network topologies generally associate VLANs with individual networks or subnetworks. However, network devices in different VLANs cannot communicate with each other without a Layer 3 switch or a router to forward traffic between the VLANs. The initial VLAN design recommends that each VLAN is associated with a different subnet as a best practice, therefore inter-VLAN routing is required to route traffic between VLANs. Cisco provides several solutions to enable inter-VLAN ...
