show ip pim rpf
Description
Reverse Path Forwarding (RPF) is used to prevent routing loops.
RPF works with the source IP address of the multicast packet and the interface on which it
was received. If a multicast packet is received on an interface, RPF checks whether the
shortest path to the multicast source is via this interface. If this condition is met, the router
forwards the packet to all multicast nodes. If the condition is not met, it discards the packet.
With this command, you display the RPF settings for a multicast packet.
