Configuring a Default Route for Unlabeled MPLS Packets
You can process 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. The process is also referred to as MPLS exception monitoring.
To configure a default label value for MPLS packets, include the default-route statement:
default-route {class-of-service cos-value;(next-hop (address | interface-name | address/interface-name) | (discard | reject);(pop | (swap out-label);preference preference;swap-push swap-label push-label;}
You can include this statement at the following hierarchy levels:
- [edit protocols mpls interface interface-name label-map]
- [edit logical-systems logical-system-name protocols mpls interface interface-name label-map]
