Displaying a list of multicast groups
To display PIM Sparse configuration information, enter the following command at any CLI level.
Syntax: show ip pim group
This display shows the following information.
Join/Prune interval How frequently the BigIron RX sends PIM Sparse Join/Prune messages
for the multicast groups it is forwarding. This field show the number of
seconds between Join/Prune messages.
The BigIron RX sends Join/Prune messages on behalf of multicast
receivers who want to join or leave a PIM Sparse group. When forwarding
packets from PIM Sparse sources, the BigIron RX sends the packets only
on the interfaces on which it has received join requests in Join/Prune
messages for the source’s group.
You can change the Join/Prune interval if needed. Refer to “Changing
the PIM join and prune message interval” on page 615.
SPT Threshold The number of packets the BigIron RX sends using the path through the
RP before switching to using the SPT path.
PIM Sparse interface information
NOTE: You also can display IP multicast interface information using the show ip pim interface command. However,
this command lists all IP multicast interfaces, including regular PIM (dense mode) and DVMRP interfaces.
The show ip pim sparse command lists only the PIM Sparse interfaces.
Interface The type of interface and the interface number. The interface type can
be one of the following:
• Ethernet
• VE
The number is either a port number (and slot number if applicable) or
the virtual interface (VE) number.
TTL Threshold Following the TTL threshold value, the interface state is listed. The
interface state can be one of the following:
• Disabled
• Enabled
Local Address Indicates the IP address configured on the port or virtual interface.
