Statement introduced in Junos OS Release 14.1.
Define the backup selection policy for a specific primary next hop.
For the explicitly configured evaluation order, only the listed attributes influence the selection of the backup path.
[root dest] — Backup path selection or preference is first based on the root-metric criteria. If the criteria of all the root-metric is the same, then the selection or preference is based on the dest-metric.
[dest root] — Backup path selection or preference is first based on the dest-metric criteria. If the criteria of all the dest-metric is the same, then the selection is based on the root-metric.
By default, backup paths with lower destination metric criteria are selected or preferred. If the criteria is the same, then the lowest root metric criteria is preferred or selected.
If no protection-type is configured, then by default the first best path that matches all the other criteria is executed.
The remaining statements are explained separately. See CLI Explorer.
