Re: ACL to permit Multicast

Hi,

Adding to Steve's post,
- CGMP frames are Ethernet frames, so you cant match it in an IP ACL.

http://www.cisco.com/en/US/products/hw/switches/ps708/products_tech_note09186a00800b0871.shtml#cgmp
- MSDP (TCP port 639)
- MOSPF (Multicast Extensions to OSPF)
- Auto-RP, BSR, Anycast RP ( All use PIM + IGP)
- IPv6 MLD ( uses ICMPv6, IP protocol 58)
