3.6 Preference Option for Standby Secondary
LSP Paths
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.
