I have been asked to implement multicast within our network tomorrow and just wanted to ask a few questions.
We have a 3550 core (HSRP) and 2950 and 3560 poe switches for the access layers.
I was proposing to configure the core as per:
ip pim send-rp-announcce vlan1 scope 16 ip pim send-rp-discovery scope 16
interface vlan 1
Then on the access switches
int vlan 1
ip pim sparse-mode
ip cgmp enable
But I do not know if i should enable igmp snooping on the access switches for if the IGMP on the core is enough to stop the multicast propogating.
I also didn't know whether to duplicate the config on the hsrp other switch.
Thanks for any advice
