Adding MPLS Support to VLANs

To use MPLS on a VLAN, MPLS must first be configured on that VLAN.
To configure a specific VLAN or all VLANs, use the following command:
configure mpls add {vlan} vlan_name

MPLS must be configured on a VLAN before it can be used to transmit or receive MPLS-encapsulated frames. By default, MPLS is not configured on a newly created VLAN.

If you have enabled MPLS on an OSPF interface that is used to reach a particular destination, make sure that you enable MPLS on all additional OSPF interfaces that can reach that same destination (for example, enable MPLS on all VLANs that are connected to the backbone network).
