Well, in IPv4 on IOS you want both MSDP filtering and "ip multicast
boundary", which filters both PIM control and data-plane traffic.
Sadly it would appear IOS has dropped ACLs for boundary on PIM6, and
assumed that the IPv6 mcast scope is sufficient for all use-cases!
NX-OS has "ipv6 pim jp-policy" and "match ipv6 multicast" options in
route-map, but this seems to be lacking from IOS.
JunOS of course has it.
It seems you can't do this right now on Cisco IOS?
