  1. Hi René,
    Under the loopback. what exact command? Is i pim proxy-server or service?

  2. Hi Rene,

    In the picture, R2 has two interfaces Gi0/2, and I think interface towards R3 should be Gi0/1

    FYI

  3. Hi Ulrich,

    Here’s the loopback of R2:

    interface Loopback0
     ip address 2.2.2.2 255.255.255.255
     ip pim sparse-mode
     ip igmp helper-address udl GigabitEthernet0/2
     ip igmp proxy-service
    

    You can find the complete configurations of all routers at the end of the lesson :smiley:

  4. R2(config-if)#ip igmp helper-address udl GigabitEthernet 0/2

    ip igmp helper-address udl: this command tells the router to send IGMP membership reports to an upstream router that is connected on our UDL interface.
    Why are we forwarding traffic to R2 Gig 0/2 towards R1 Gig 0/2 when R1 is blocking all income traffic?

    R2(config-if)#ip igmp unidirectional-link

    If it is unidirectional how would we know if traffic is inbound or outbound only?

    Thanks

  5. Hello Mark.

    The lesson here is simulating a situation where there is a unidirectional link such as is often the case when using satellite connections. All traffic on the satellite link goes from the internet towards the user, whereas all upload data goes via an alternate physical link. So, in order to simulate this situation, all incoming data on R2 G0/2 interface is blocked.

    Having said that, let’s get to your questions:
