Setting the Probe Timer
The probe timer specifies the interval, in seconds, between the time that the
first-hop router sends a probe packet to the RP router and the expiration of the
register suppression timer.
Before the register suppression timer times out, the first-hop router sends a probe
packet to the RP. If the RP determines that it still does not have any downstream
receivers, it sends a register-stop message back to the first-hop router, thereby
restarting the suppression timer. If the first-hop router does not receive a
register-stop message in response to the probe, the suppression timer expires and
the first-hop router re-creates the outgoing interface for this entry so that future
register packets can be forwarded to the RP router.
By default, PIM sets the probe timer to 5 seconds. You can set the probe timer
from 1 through 65,535 seconds (18 hours, 12 minutes, and 15 seconds). This value
must be less than the value you specify for the register suppression timer.
Otherwise, the probe timer has no effect and the register suppression timer times
out.
To set the probe timer, complete the following tasks:
