Enabling multicast routing in cisco2960S lan switch

Hi

Firstly you have to know that only routers or L3 devices which is used for  Multicast . For l2 swtches ony used for unicast or igmp join multicast . So based on the above post , all are ok except (ip pim sparse-dense-mode).you need for Cisco switches igmp join to join your multicast. IP pim sparse-mode is required under l3 interface devices which is participate in multicast routing.

Thank you
