Configure the LSP Preference

As an option, you can configure multiple LSPs between the same pair of ingress and egress routers. This is useful for balancing the load among the LSPs because all LSPs, by default, have the same preference level. To prefer one LSP over another, set different preference levels for individual LSPs. The LSP with the lowest preference value is used. The default preference of all LSPs is 7, which is lower (more preferred) than all learned routes except for direct interface routes.

To change the default preference value, include the preference statement at the [edit protocols mpls], [edit protocols mpls label-switched-path lsp-path-name ], or [edit protocols mpls label-switched-path lsp-path-name (primary | secondary)] hierarchy level:

preference preference ;
