(msec)
Propagation Delay 500
vlan < vid > ip pim-dense propagation-delay < 250-2000 >

SR TTL Threshold
0

(router hops)
LAN Prune Delay
Yes
vlan < vid > ip pim-dense lan-prune-delay
LAN Delay Enabled No
Shows
Yes
if all multicast routers on the current VLAN
interface enabled LAN-prune-delay. Otherwise shows
No
.
State Refresh
n/a
Indicates whether the VLAN responds to state refresh
Capable
packets. The VLAN connected to the multicast source does
not receive state refresh packets and thus is not state-refresh
capable. Downstream VLANs in the switches covered in this
guide are state-refresh capable.
Syntax: show ip pim [mroute]
Shows PIM-specific information from the IP multicast
routing table (IP MRT). When invoked without parameters,
lists all PIM entries currently in the routing switch’s IP MRT.
Group Address: Lists the multicast group addresses currently
active on the routing switch.
Source Address: Lists the multicast source address for each
Group 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. This value is set to
0 (zero) for
directly connected routes.
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.
This value is set to
0 (zero) for directly connected routes.
(
Metric Pref is based on the routing protocol in use: RIP, OSPF,
or static routing. Also, different vendors may assign different
values for this setting.)
