  1. Hi Rene

    First of all thanks a lot or sharing your knowledge. Your way of explanation is very simple & concise. Before start learning any particular topics ya concept, i check ur blog posting includes that topic or not. Jst now i find, Bi Directional PIM. Its so nice to learn from ur blogs. Appreciate the efforts. Thanks a lotzzzzzz…

  2. While labbing the same topology, i found something diff from ur configuration. Here it is:

    1. “ip pim bidir-enable” should be enable on R4 & R5 as well.
    2. “ip pim rp-address bidir” should be configured on R4 & R5 as well.

    Then only i am getting the same output as u mention in your most. Let me know i have done mistakes anywhere ya i understood it wrongly.

    I really enjoy the way you teach and the content is very well organized.
    I have a question regarding PIM Bidirectional.
    For have in all Pim enabled Router the *,G to the RP on downstream Router, we need to enable globally the pim bidirectional.
    What if i have on third party router that doesnt’ support pim bidirectional? is it will be enable to from *,G to the RP?

  4. Hi Rene,

    I do not understand based on the last output shown below
    (Now we see FastEthenet0/0 as the Bidir-Upstream interface and FastEthernet0/1 in the outgoing list. This is something different than what you have seen before right?)

    Isn’t your earlier output already showing FastEthenet0/0 as the Bidir-Upstream interface and FastEthernet0/1 in the outgoing list?

    R3#show ip mroute
