(Optional) Changing the PSB and RSB Timeout Multiplier
Context
To help allow TE FRR to operate during the RSVP GR process, the timeout multiplier of the Path State Block (PSB) and Reservation State Block (RSB) can be set. The setting prevents the situation where information in PSBs and RSBs is dropped due to a timeout before the GR processes are complete for a large number of CR-LSPs.
Perform the following configurations on the PLR.
Procedure
- Run system-view
The system view is displayed.
- Run mpls
The MPLS view is displayed.
- Run mpls rsvp-te keep-multiplier keep-multiplier-number
The PSB and RSB timeout multiplier is set.
The default timeout multiplier is 3.
Setting the timeout multiplier to 5 or greater is recommended for a network where a large number of CR-LSPs are established and RSVP GR is configured.
