Basic MPLS Configuration

This section provides information to configure MPLS and gives configuration examples of common configuration tasks. To enable MPLS on a 7705 SAR router, you must configure at least one MPLS interface. The MPLS interface is configured in the config>router> mpls context. The other MPLS configuration parameters are optional.

The following example displays an MPLS configuration output. The admin-group is configured in the config>router>if-attribute context and associated with the MPLS interface in the config>router>mpls>interface context.
