♦ Interface Mask – Masks all or part of the IP address of PIM ports.
♦ Designated Router – Identifies the designated router on each multi-access router. The
designator router polls the LAN to determine group membership. The router with the highest IP
address is the designated router. If the designated router times out, a new designated router is
elected from the alternate PIM routers. Designated routers are only needed for multi-access
networks and not point-to-point links. Point-to-point links show a value of 0.0.0.0.
♦ Hello Interval – Indicates in seconds the amount of time ports send hello messages. PIM-DM
routers keep track of neighboring interfaces based on received hello messages. Neighbor
information is deleted if there it is not refreshed before expiration. The default time is 30
seconds.
♦ JoinPrune Intervals – Indicates the intervals at which Join/Prune messages are sent to the
PIM router. The PIM router assumes that all downstream routers can receive multicast packets,
flooding the network with multicast packets. If specific network areas do not have multicast
group members, PIM-DM prunes off the forwarding branch by establishing a Prune state. The
Prune state contains the source and multicast group address, and contains a timer. When the
timer expires the network branch goes into a forwarding state. The default is 210 seconds.
