%LINEPROTO-5-UPDOWN: Line protocol on Interface GigabitEthernet0/0, changed state to up %LINK-5-CHANGED: Interface GigabitEthernet0/0, changed state to up Router(config)# interface gigabitethernet0/0 For example gigabitethernet0/0.10 is a subinterface targeted to the VLAN10. When creating a subinterface, you can type the number of the VLAN ID to avoid confusion next to the port and slot number of the respective interface. VLAN Routing on Cisco SwitchĪt the CLI command prompt of the Cisco Router, execute the following commands to create Subinterface for the interface that connects to the Switch. After designing your network topology, create VLANs called VLAN10, VLAN20, and VLAN30 on Cisco Switch and add management IP addresses.įollow the steps below in order to enable routing between new VLANs you have created. Now, create a network topology as in Step 1 on the Cisco simulator software. This method is not recommended as using more cables will result in both reducing the number of empty interfaces on the Router and increasing the cost of the cable. If there is a Layer 3 Switch in the network environment, all you need to do for routing to VLANs is to execute ip routing in config mode.Īnother way to enable VLAN routing is to plug in more cables from the Switch to the Router. The subinterface configured interface accepts traffic from all VLANs. In order to enable routing between VLANs, subinterfaces are created according to the IP addresses of the VLANs in the interface connected to the Switchport of the Router and routing is provided. The Switchport connected to the router is configured as a trunk port. Router-on-a-Stick is the second type of Inter-VLAN routing, and the Router is connected to the Switch with a single interface.
