Description

PIM snooping snoops PIM hello and join/prune packets on each interface to find interested multicast receivers and then populates the multicast forwarding tree with the information. PIM snooping is configured on PE routers connected using pseudowires and ensures that no new PIM packets are generated in the VPLS (with the exception of PIM messages sent through LDP on pseudowires). PIM snooping differs from PIM proxying in that PIM snooping floods both the PIM hello and join/prune packets in the VPLS, whereas PIM proxying only floods hello packets.

Default

PIM snooping is disabled on the device.

Options

no-dr-flood

Disable default flooding of multicast data on the PIM-designated router port.

traceoptions

Configure tracing options for PIM snooping.

vlan <vlan-id>

Configure PIM snooping parameters for a VLAN.

Required Privilege Level

routing—To view this statement in the configuration.

routing-control—To add this statement to the configuration.

Release Information

Statement introduced in Junos OS Release 12.3.
