On monitoring services interfaces, you can process Multiprotocol Label Switching (MPLS) packets that have not been assigned label values and have no corresponding entry in the mpls.0 routing table. This allows you to assign a default route to unlabeled MPLS packets.
To configure a default label value for MPLS packets, include the default-route statement at the [edit protocols mpls interface interface-name label-map] hierarchy level:
- [edit protocols mpls interface interface-name label-map]
- default-route {
- (next-hop (address | interface-name | address/interface-name)) | (reject | discard);
- (pop | (swap <out-label>);
- class-of-service value;
- preference preference;
- type type;
- }
For more information about static labels, see the JUNOS MPLS Applications Configuration Guide.
