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

    3.    ipv6 multicast pim-passive-enable

    4.    interface type number

    5.    ipv6 pim passive


DETAILED STEPS
    Step 1   enable


    Example:
    Device> enable

    Enables privileged EXEC mode.

    • Enter your password if prompted.

    Step 2   configure terminal


    Example:
    Device# configure terminal

    Enters global configuration mode.

    Step 3   ipv6 multicast pim-passive-enable


    Example:
    Device(config)# ipv6 multicast pim-passive-enable

    Enables the PIM passive feature on an IPv6 device.

    Step 4   interface type number


    Example:
    Device(config)# interface GigabitEthernet 1/0/0

    Specifies an interface type and number, and places the device in interface configuration mode.

    Step 5   ipv6 pim passive


    Example:
    Device(config-if)# ipv6 pim passive

    Enables the PIM passive feature on a specific interface.
