Switch(config)#router ip_routing_protocol Step 4 : Configure the IP routing protocol if needed. Switch(config)#interface vlan vlan-id Step 2 : Create an SVI interface. Switch(config-if)#ip address ip-address mask Step 3 : Assign an IP address to the SVI.

Specific commands are used to configure and verify routing on multilayer switch interfaces. The interface vlan command creates the SVI. A routed port has Layer 3 attributes. A routed port requires the removal of Layer 2 port functionality with the no switchport command. To receive dynamic updates, a routing protocol is required.
