H3 Multicast Questions and Solution with Variations

[cciecandidate]

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
