How to Configure IP Routing with Layer 3 Switch SVI

In this video, the presenter demonstrates how to configure Layer 3 routing using Switch Virtual Interfaces (SVIs). The setup involves creating three VLANs: VLAN 1 for PC1, VLAN 2 for another PC, and VLAN 3 for WAN access. The presenter first assigns VLANs to specific interfaces on a Layer 3 switch and configures IP addresses for each VLAN interface. The IP address for VLAN 1 is set to 192.168.10.1, for VLAN 2 to 192.168.20.1, and for VLAN 3 to 192.168.30.1. Initially, devices cannot communicate across VLANs because IP routing is disabled. The presenter then enables IP routing, allowing the VLAN interfaces to act as gateways and enabling inter-VLAN communication. To facilitate communication with the WAN, the presenter assigns an IP address to the router and updates the routing table to include static routes for the VLANs. After configuring the necessary routes, the devices can ping each other and communicate with the router. The video concludes with a demonstration of how to trace the route taken by packets, confirming successful configuration.
