1、Lab 42 InterVLAN Routing with an Internal Route Processor andLab 4-2 Inter-VLAN Routing with an Internal Route Processor andMonitoring CEF FunctionsTopology DiagramObjectiveThis lab routes between VLANs using a 3560 switch with an internal routeprocessor using Cisco Express Forwarding (CEF).Scenario

2、The current network equipment includes a 3560 distribution layer switch andtwo 2960 access layer switches. The network is segmented into three functionalsubnets using VLANs for better network management. The VLANs includeFinance, Engineering, and a subnet for equipment management, which is thedefaul

3、t management VLAN, VLAN 1. After VTP and trunking have beenconfigured for the switches, Switched Virtual Interfaces (SVI) are used on thedistribution layer switch to route between these VLANs, giving full connectivityto the internal network.2 - 13 CCNP: Building Multilayer Switched Networks v5.0 - L
