Usage
Information
Because PIM-SM snooping is used in a Layer 2 environment, PIM-SM snooping and PIM
multicast routing are mutually exclusive. PIM-SM snooping cannot be enabled on a switch/
router if PIM-SM or PIM-DM is enabled.
If enabled at the global level, PIM-SM snooping is automatically enabled on all VLANs
unless the no ip pim snooping command has been entered on a VLAN.
If enabled at the VLAN level, PIM-SM snooping requires that you also enter the no
shutdown command to enable the interface.
PIM-SM snooping is supported with IGMP snooping, and forwards the IGMP report on the
port that connects to the PIM DR. It is recommended that you do not enable IGMP snooping
on a PIM-SM snooping-enabled VLAN interface unless until it is necessary for VLAN
operation.
