Q3 Single choice

You have established an MSDP peering between multicast domains for your AS and a neighboring AS.
You are concerned about unnecessary flooding or looping of source active messages between MSDP peers.

Which MSDP mechanism is used to prevent this problem?

  • A

    The receiving MSDP peer performs a multicast RPF check to ensure that the SA messages are forwarded away from only the originating multicast source.

  • B

    The receiving MSDP peer sends register-stop messages towards the originating RP that forwarded the
    SA messages.

  • C

    The receiving MSDP peer performs amulticast peer-RPF check to ensure that the SA messages are forwarded away from only the originating RP.

  • D

    The receiving MSDP peer sends prune messages to all upstream neighbors to avoid receiving

    additional SA messages.
