3.6 Preference Option for Standby Secondary

The path-preference command allows priority values to be assigned to standby

secondary LSP paths. This command can only be used for secondary LSP paths that

have been configured in standby mode.

When the primary LSP becomes inactive, the standby secondary LSP with the

highest path priority (lowest path-preference value) is chosen from the qualifying

standby secondary LSPs to become the active LSP. This functionality allows a user

to choose a path for one of the standby secondary LSPs that may, for example, be

over a more reliable link or over a link with a lower latency.

If multiple standby secondary LSP paths have the same priority value, the system

selects the path with the lowest uptime.
