RSVP Commands
The head-end LER node upon receipt of the updates IPG TE LSA/LSP for the maintenance interfaces
updates the TE database. This information will be used at the next scheduled CSPF computation for
any LSP which path may traverse any of the maintenance interfaces.
The no form of the command disables the graceful shutdown operation at the RSVP interface level or
at the RSVP level. The configured TE parameters of the maintenance links are restored and the
maintenance node floods the links.
Default none
gr-helper-time
Syntax gr-helper-time max-recovery recovery-interval [1..1800] seconds max-restart restart-
interval [1..300] seconds

The no version of this command re-instates the default value for the delay timer.
Parameters recovery-interval — Specifies the max recovery interval value in seconds.
restart-interval — Specifies the max restart interval value in seconds.

interface(s)/node(s).
c. A CSPF LSP with the adaptive option disabled and which current path is over the listed
maintenance interfaces in the PathErr message. These are not subject to make-before-break.
d. A non CSPF LSP which current path is over the listed maintenance interfaces in the PathErr
message.
