[c-nsp] Equivalent of "ip multicast boundary" on N7k for blocking data packets?

In n7k, you must use a combination of control plane & data plane 
filtering to get the equivalent functionality of multicast boundary.

For data plane, it's nothing more than ip access-group with matches 
on multicast traffic.

For control plane, there is independent filtering control for each 
protocol, ie, PIM, IGMP, MSDP, etc.

Hope that helps,
Tim
