  1. Hi Rene,

    I tried to simulate the Embedded-RP but it didn’t work.
    The only stuff that worked was statically configured ipv6 pim rp-address on all the nodes.

    But i was trying to check that cool feature and what i saw is that on DR (where source is connected) there’s a constant Registering appears there and RP node itself is not seeing (S,G), only (*,G) as a part of connected receiver via MLD join-group.

    I don’t get what i’m missing here…

    I will be very thankful to you if you can reply with your suggestions what could be the problem?

    By the way does this feature s

  2. I looked at the formation of your Embedded RP, and it looks correct.

    Your RP = FC00:2:2:2::2/64
    Your Embedded RP Address: FF78:240:FC00:2:2:2:0:1. This address is correctly formatted assuming you want to use the first multicast group (then trailing 0:1) possible on that RP, and the scope of the multicast group is global (8).

    Also, your show commands have the correct output (like on the RP, for example) where it shows the correct (*,G) entry.

    The problem is your lab is extremely complicated, and frankly, I don’t want to spend two hours troubleshooting it. I su

  3. Hi Andrew,

    I checked with 3 nodes R1—R2—R3 and it worked properly. R1 (source), R2 (RP) and R3 (receiver)
    What i don’t understand is if R1 is sending the MCAST traffic, then who is DR in this scenario? R2? Who actually is sending the unicast register messages towards RP? A little bit confusing this scenario.

    I’m regular to some basic setup where R5—R1—R2—R3—R7 where (R5 is a source), (R1 a DR), (R2 is and RP), (R3 is a last hop router connected to receiver), (R7 is a receiver)

    But what i found out is if i test with 5 devices than it’s not working and DR is show

  4. Hi Andrew,

    one more update:
    It’s not working when changing the 40 to 80!
    I changed the loopback prefix to /128 (FC00:2:2:2::A/128 instead of FC00:2:2:2::A/64) and joined the following MCAST ipv6 group on receiver (ipv6 mld join-group FF78:A80:FC00:2:2:2:0:1) but RP wasn’t learned on any node and therefore the traffic didn’t flow as well.

    (*, FF78:A80:FC00:2:2:2:0:1), 00:00:03/never, RP ::, flags: SCLJ
      Incoming interface: Null
      RPF nbr: ::
      Immediate Outgoing interface list:
        GigabitEthernet1.37, Forward, 00:00:03/never

  5. Hi @ReneMolenaar In the configuration of R2 in the article Embedded RP IPv6 Multicast, I can see there is Tunnel2. What is it?

    (*, FF78:240:FC00:2:2:2:0:1), 00:05:23/never, RP FC00:2:2:2::2, flags: SCJ
      Incoming interface: Tunnel2
      RPF nbr: FC00:2:2:2::2
      Immediate Outgoing interface list:
        FastEthernet0/0, Forward, 00:05:23/never
