Re: Verizon Router Multicasting To My Home Network

I was to understand that the boxes do not use multicast. They work correctly with multicast blocked. Multicast is used on the DVR to do remote access. I don't have any DVR 's here, I have QIP 7100 P2 boxes. Jim

No, once IMG Multicast is enabled in a VHO, all the STB's will use it, not just the DVR's.

Nycdave,

Thanks, your statement indicates verizon is making changes on the back end. This would account for the behavior change I am seeing at my firewall. Do you know why this would be needed for the cable boxes?

Regards,
Jim

Unicast IMG guide data is inefficient when millions of boxes request guide data when they boot up, and it really taxes the network. Multicast helps to offload this network drain for IMG guide data.
