PIM-SM (Sparse Mode)
Displaying PIM-SM Data and Configuration Settings
Displaying a Specific PIM Entry Stored in the Multicast
Routing Table
Syntax: show ip pim mroute [< multicast-group-address >
< multicast-source-address >]
Displays the PIM route entry information for the specified
multicast group (flow):
Group Address: Lists the specified multicast group address.
Source Address: Lists the specified multicast source address.
Source Mask: Lists the network mask for the multicast source
address.
Metric: Indicates the path cost upstream to the multicast
source. Used when multiple multicast routers contend to
determine the best path to the multicast source. The lower the
value, the better the path.
Metric Pref: Used when multiple multicast routers contend to
determine the path to the multicast source. When this value
differs between routers, PIM selects the router with the lowest
value. If Metric Pref is the same between contending multicast
routers, then PIM selects the router with the lowest
Metric
value to provide the path for the specified multicast traffic.
(Different vendors assign differing values for this setting.)
Assert Timer: The time remaining until the router ceases to
wait for a response from another multicast router to negotiate
the best path back to the multicast source. If this timer expires
without a response from any contending multicast routers,
then the router assumes it is the best path, and the specified
multicast group traffic will flow through the router.
RPT-bit: A Yes setting indicates the route is using the RPT. A
No setting indicates the route is using the applicable SPT.
