multicast group joins between PIM-SM domains

kjbarrass

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

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,
