PIM-SM (Sparse Mode)
Configuring PIM-SM on the Router
Changing the Randomized Delay Setting for
PIM-SM Neighbor Notification
Syntax: ip pim-sparse hello-delay < 0 - 5 >
vlan < vid > ip pim-sparse hello-delay < 0 - 5 >
Changes the maximum time in seconds before the router
actually transmits the initial PIM Hello message on the
current VLAN. In cases where a new VLAN activates with
connections to multiple routers, if all of the connected
routers sent Hello packets at the same time, then the
receiving router could become momentarily overloaded. This
value randomizes the transmission delay to a time between
0 and the hello delay setting. Using “0” means no delay. After
the router sends the initial Hello Packet to a newly detected
VLAN interface, it sends subsequent Hello packets according
to the current
Hello Interval setting. Not used with the no form
of the ip pim command. (Default: 5 seconds.)
Changing the PIM-SM Neighbor Timeout Interval
Syntax: ip pim-sparse nbr-timeout < 60 - 65535 >
vlan < vid > ip pim-sparse nbr-timeout < 60 - 65535 >
Changes the timeout interval allowed between successive
Hello messages from a PIM-SM neighbor (in seconds) after
which the neighbor will be considered unreachable.
(Default: 180 seconds.)
