Modifying the PIM Router-Query Message Interval (CLI)
PIM routers and multilayer devices send PIM router-query messages to find which device will be the designated
router (DR) for each LAN segment (subnet). The DR is responsible for sending IGMP host-query messages
to all hosts on the directly connected LAN.
With PIM DM operation, the DR has meaning only if IGMPv1 is in use. IGMPv1 does not have an IGMP
querier election process, so the elected DR functions as the IGMP querier. With PIM-SM operation, the DR
is the device that is directly connected to the multicast source. It sends PIM register messages to notify the
RP that multicast traffic from a source needs to be forwarded down the shared tree. In this case, the DR is the
device with the highest IP address.
This procedure is optional.
