Minimum MPLS Configuration

To enable MPLS on the router, you must include at least the following statements. This minimum configuration enables MPLS on a logical interface. All other MPLS configuration statements are optional. Note that this configuration does nothing more than enable MPLS on the router and on the specified interface.

Include the family mpls statement:

family mpls;

You can include this statement at the following hierarchy levels:

  • [edit interfaces interface-name unit logical-unit-number]
  • [edit logical-systems logical-system-name interfaces interface-name unit logical-unit-number]

Include the interface in the MPLS and RSVP protocol configuration:

mpls { interface (interface-name | all); # Required to enable MPLS on the interface}rsvp { # Required for RSVP-signaled MPLS onlyinterface interface-name;}

You can configure these statements at the following hierarchy levels:

  • [edit protocols]
  • [edit logical-systems logical-system-name protocols]

For every interface you enable, two special routes are installed automatically in the MPLS forwarding table. One route has a label value of 0, and the second has a label value of 1. (For information about these labels, see Special Labels.)
