The mpls rsvp-te srefresh command enables summary refresh (Srefresh).
The undo mpls rsvp-te srefresh command disables Srefresh.
By default, Srefresh is disabled.
Usage Scenario
Srefresh messages are used to refresh states carried in Message_ID objects in Path and Resv messages. Using Srefresh is recommended, reducing Path and Resv message costs.
Configuration Impact
Enabling Srefresh to refresh Path and Resv messages disables the original refresh function.
