PIM-SM (Sparse Mode)
Displaying PIM-SM Data and Configuration Settings
Listing All VLANs Having Currently Active PIM Flows
Syntax: show ip mroute interface [< vid >]
Lists these settings:
VLAN: The VID specified in the command.
Protocol: PIM-SM or PIM-DM.
TTL: The time-to-live threshold for packets forwarded through
this VLAN. When configured, the router drops multicast pack­
ets having a TTL lower than this value. (When a packet
arrives, the router decrements it’s TTL by 1, then compares
the decremented packet TTL to the value set by this command.)
A
TTL Threshold setting of 0 (the default) means all multicast
packets are forwarded regardless of the TTL value they carry.
A multicast packet must have a TTL greater than 1 when it
arrives at the router. Otherwise the router drops the packet
instead of forwarding it on the VLAN.
