Object
column
r/w
PimGrTimerValue
The length of the Graceful Restart backstop timer to run
within DC-PIM, in seconds.
Graceful Restart is currently only supported when running
in IGMP Proxy, IGMP Snooping, Sparse and Dense modes - see
pimTmEntMode. Note that in Sparse/Dense mode, the
Backstop Duration must be greater than the Join Startup
Duration, pimTmEntGRJoinStartupDuration.
In IGMP Graceful Restart, processing is normally timed out
by suitable protocol timers (e.g. IGMP Startup Query
Interval), but this timer is provided as a backstop to
allow the administrator to override any protocol timers.
In PIM Graceful Restart, if the network is stable,
processing is a finite action. However, when the network
is unstable, data flows may change frequently enough to
put DC-PIM in a permanent state of audit. The backstop
timer overrides any excess processing, causing DC-PIM to
break out of audit on expiry.
This field together with pimTmEntGRJoinStartupDuration
defines whether Graceful Restart is supported for this
DC-PIM instance. If both of them are set to 0 then
Graceful Restart is disabled and DC-PIM will not attempt
to preserve data plane state on restart.
The default value is 0 seconds, meaning that Graceful
Restart is disabled.
