We do not need any other Layer 3 device for VLAN Routing with Layer 3 Switch. Because Layer 3 switch can achieve this routing facility. Here, instead of subinterface, “VLANIF” is created for each VLAN.
Our example topology is below:
This VLANIF is used as the gateway of each VLAN.So, we have 3 VLANs and we need to create 3 VLANIF.
Let’s start the configuration.
Layer 3 Switch Configuration for VLAN Routing
Firstly we will configure, each interfaces of the L3 Switch. We will set these interfaces as access and we will give their default VLAN.
