I have to setup multicast in our LAN network for which I need some desing and configuration examples specifically for LAN. This setup would be simple as we have 2 Cisco 6509 in core/distribution and 3560s as access layer swicthes. Multicast servers will be connected directly with core switch. What would be the recommended PIM mode I should use here in this scenario ? Only layer 3 device in this scenario is cisco 6509 switch which is trunked with multiple access layer ( 3560s ) switches.
