Figure 6- 147. PIM Interface Table window
The
PIM Interface Table displays the following fields:
IfIndex –
Specifies the PIM port number.
Interface Address – Indicates the IP address of the PIM port.
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.
