RSVP Commands
The node performs a single make-before-break attempt for all adaptive CSPF LSPs it originates and
LSP paths using the maintenance interfaces. If an alternative path for an affected LSP is not found,
then the LSP is maintained on its current path. The maintenance node also tears down and re-signals
any detour LSP path using listed maintenance interfaces as soon as they are not active.
The maintenance node floods an IGP TE LSA/LSP containing Link TLV for the links under graceful
shutdown with Traffic Engineering metric set to 0xffffffff and Unreserved Bandwidth parameter set
to zero (0).
A head-end LER node, upon receipt of the PathErr message performs a single make-before-break
attempt on the affected adaptive CSPF LSP. If an alternative path is not found, then the LSP is
maintained on its current path.
A node does not take any action on the paths of the following originating LSPs after receiving the
PathErr message:
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
keep-multiplier
Syntax [no] keep-multiplier number
no keep-multiplier
Context config>router>rsvp
Description
The keep-multiplier number is an integer used by RSVP to declare that a reservation is down or the
neighbor is down.
The no form of this command reverts to the default value.
Default 3
Parameters
number — The keep-multiplier value.

Guide
a. An adaptive CSPF LSP for which the PathErr indicates a node address in the address list and
the node corresponds to the destination of the LSP. In this case, there are no alternative paths
which can be found.
b. An adaptive CSPF LSP whose path has explicit hops defined using the listed maintenance
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.
