Usage Guidelines
In the event of a path failure, the secondary frequency value is used instead of the normal frequency value.
The normal frequency value is determined by a frequency value or schedule period value, and the LSP
operations are scheduled to start periodically at this interval. By default, the secondary frequency value is
disabled. When failure condition disappears, probing resumes at the regular frequency.
The secondary command works in tandem with the retry keyword. Both must be configured.
