Layer 3 switches are much more cost effective than routers for delivering high-speed inter-VLAN
•
routing.
Layer 3 switches are enhanced Layer 2 switches, and therefore have the same high port
•
densities as Layer 2 switches. Routers on the other hand typically have a much lower port
density.
Layer 3 switches can be configured to operate as a normal Layer 2 switch or Layer 3 switch as
•
required.
Application of Inter-VLAN routing:
The network can be divided based on the group or function of itsdevices. For example, an engineering
department VLAN would only have devices associated with the engineering department, while an HR
VLAN would only have HR related devices. With Inter-VLAN routing, the devices in each VLAN can talk to
one another without all the devices being in the same broadcast domain.

Figure IP-1: Inter-VLAN Routing
Follow the steps below to configure Inter-VLAN routing.
1. Create two Layer 3 interface VLANs.
2. Configure an IP address for both interfaces of these Layer 3 VLANs.
3. Execute show ip route to check if the VLAN routes specified by VLAN IP address are displayed as
connected routes. The routing table has an entry for each VLAN interface subnet, therefore,
devices in VLAN 10 can communicate with devices in VLAN 20 and vice versa.
The example below shows the commands used to configure Inter-VLAN routing.
