Inter VLAN Routing in L3 Switches

Inter-VLAN routing using a Layer 3 switch is simpler to configure than the router-on-a-stick method. After the configuration is complete, the configuration can be verified by testing connectivity between the hosts. From a host, verify connectivity to a host in another VLAN using the ping command

Switch#configure terminal
Enter configuration commands, one per line. End with CNTL/Z.
