multicast group joins between PIM-SM domains

when you have two PIM-SM domains peering with each other using MSDP, how does one PIM domain join a group in the other PIM domain it knows about via MSDP. Does it use IGMP between the domains or is this part of MSDP.

Kind Regards

Kev

Re: multicast group joins between PIM-SM domains

PIM joins are used between the two domains just as they are within a single domain. IGMP is only used between the multicast receiver and its local router.

Hope this helps,
