  1. Hi Rene,

    What is the different PIM accept RP and below configuration? The PIM accept RP applicable for static RP, Auto Rp and BSR?

    Ip PIM send-rp-annouce loopback 0 scope 10 group-list 1

  2. Hi Davis,

    PIM accept RP can be used to tell your router not to accept just any RP. I believe it works for AutoRP and BSR, not for static RPs. For example when there are 10 routers in your network advertising themselves as the RP then you can use this command to ignore a couple of them.

    ip pim send-rp-announce is used to configure your router to advertise itself as an RP, the access-list is used to advertise the networks that you want to be a RP for.

  3. Hi Hans,

    192.168.12.1 is the IP address of R1. I usually use subnets / IP addresses like this:

    192.168.XY.X where X = R1 and Y = R2.

    For loopbacks I use 1.1.1.1/32 for R1, 2.2.2.2/32 for R2 etc.

  4. Hi Rene,

    What if I sourced the Multicast traffic from R1 Loopback, will it accept, for my lab its not accept and showing RPF failed or RP failed from debug, even though R2 has correc RPF.

  5. Hi Jam,

    It doesn’t matter if you use a loopback or “regular” interface as the source as long the RPF check is correct. It’s difficult to tell what is wrong without seeing your config.
