VLAN Assignments

VLAN Assignments
The command to establish a VLAN is used only if an external router’s interface is not using ISL
or 802.1Q encapsulation. (RSMs and MSFCs use logical VLAN interfaces.) An example is a
router that has two physical interfaces connected to the same switch, each to a different VLAN.
This scenario doesn’t require that the router be aware of VLAN assignments and would typically
be found on routers that have only 10Mb interfaces.
Configuring MLS-RP 567
If you wish to enable MLS on interfaces that don’t use VLANs, you can issue the mls rp
vlan-id vlan_id_number command to assign a VLAN to the interface. Here’s an example:
Terry_2620#configure terminal
Enter configuration commands, one per line. End with CNTL/Z.
Terry_2620(config)#interface fastethernet 4/0
Terry_2620(config-if)#mls rp vlan-id 10
Terry_2620(config-if)#^Z
Terry_2620#
