IPv6 PIM Passive Mode

This feature allows PIM passive mode to be enabled on an interface so that a PIM passive interface cannot send and receive PIM control messages, but it can act as a reverse path forwarding (RPF) interface for multicast route entries, and it can accept and forward multicast data packets.

Information About IPv6 PIM Passive Mode

A device configured with PIM will always send out PIM hello messages to all interfaces enabled for IPv6 multicast routing, even if the device is configured not to accept PIM messages from any neighbor on the LAN. The IPv6 PIM passive mode feature allows PIM passive mode to be enabled on an interface so that a PIM passive interface cannot send and receive PIM control messages, but it can act as RPF interface for multicast route entries, and it can accept and forward multicast data packets.

How to Configure IPv6 PIM Passive Mode

SUMMARY STEPS

  1. enable
  2. configure terminal
