PIM-SSM Group

To define the Source Specific Multicast (SSM) range of IP multicast addresses, use the
following command. When an SSM range of IP multicast addresses is defined by the ip
pim ssm command, no Multicast Source Discovery Protocol (MSDP) Source-Active (SA)
messages will be accepted or originated in the SSM range.
Command
ip pim ssm range {<1-99> | AC-
CESS-LIST}
ip pim ssm default
no ip pim ssm

PIM Snooping

PIM Snooping is used to reduce unnecessary bandwidth by restricting data and multicast
control packets which transmitted between each port. In networks where a Layer 2 switch
interconnects several routers, the switch floods IP multicast packets on all multicast router
ports by default, even if there are no multicast receivers downstream. If PIM Snooping is
enabled, the switch restricts multicast packets for each IP multicast group to only those
multicast router ports that have downstream receivers joined to that group. And the switch
learns which multicast router ports need to receive the multicast traffic within a specific
VLAN by listening to the PIM hello messages, PIM join and prune messages.
To configure PIM Snooping, use the following command.
Command
ip pim snooping
ip pim snooping vlan VLANS
no ip pim snooping
no ip pim snooping vlan VLANS
To delete all L2 PIM snooping multicast groups of a specified port, multicast address or
vlan, use the following command.
Command
clear ip pim snooping groups
[A.B.C.D]
clear ip pim snooping groups
[ port PORTS]
clear ip pim snooping groups
[ vlan VLANS]
By default, PIM Snooping is disabled. To operate PIM Snooping, IGMP Snooping should
be enabled as well.
