H3 Multicast Questions and Solution with Variations

Dears,

I would appreciate if someone provide updated H3 Multicast Questions and Solution with Variations. Especially, the filtering of RP announcements in DC!

I tried to make an access list

Access-list 101 deny ip any host 224.0.0.39
Access-list 101 deny ip any host 224.0.0.40
Access-list 101 permit ip any any


R10,R11


int e0/0
ip multicast boundary 101 in

Nothing is being filtered in DC side!

Thanks

This is correct solution:
//in R30:
access-list 1 permit 239.130.0.0 0.0.255.255
ip pim send-rp-ann loopback1 scope 1 group-list 1
ip pim send-rp-dis loopback1 scope 2

//in R30, R31:
access-list 2 deny 239.130.0.0 0.0.255.255
access-list 2 permit any
!
int eth 0/0
ip multicast boundary 2 filter-autorp

Thank you for your reply.

Will ip multicast boundary 2 filter-autorp filter RP messages IN and OUT for 239.130.0.0/16 ? Or it is just IN ?
