Re: ACL to permit Multicast

Thanks Steve...so I think I can assume they wont mix the security part with
multicast part in the lab :) bcz most of the time we permit only routing
updates and sometimes ICMP before we start to put the deny rules

still if we are permitting ip bet the source /destination then everything
should be working

Thanks

  Copying Group:

  PIM is only one protocol within the suite of protocols. Keep in mind there
is also CGMP, IGMP, MSDP, MOSPF, Auto-RP, BSR, Anycast-RP, and in IPV6 MLD.
There are also a range of multicast addresses you could allow:
