Hi,

I have a question regarding multicast group scoping. Can someone please help me understand what the following requirement implies?

- Configure R3 to assign R1 as the RP for the groups in the range 224.0.0.0/5, and R2 as the RP for groups in range 232.0.0.0/5. Groups in administratively scoped mcast range should not be distributed throughout the multicast domain.

I have a problem with the /5 mask, - how do you calculate which groups that will be covering in this case?!

And, once calculated, - can you rp-filter on the BSR router similar to that of auto-rp with rp-announce-filter?

Thanks for you help!
