configure pim dense-neighbor-check

configure pim dense-neighbor-check [on | off}


This command is used to configure a PIM interface that receives multicast data traffic. It could be either from a source directly connected or from a PIM neighbor. In the second case (from a source not directly connected), if the received interface has no PIM neighbor, the traffic is dropped (default behavior). If you turn off this check, the traffic is processed.

Syntax Description

dense-neighbor-check Check if multicast traffic is received from PIM neighbor in dense mode.
on Drop multicast traffic if not received from PIM neighbor (default).
off Forward multicast traffic even if not received from PIM dense neighbor.


The default is on.


The following example turns on dense neighbor check:

configure pim dense-neighbor-check on
