We have two servers communicating with multicast between 3 6500's (2 access and 1 Distribution). On one access 6500 its using CatOS and the other access its using IOS. Between the two access switchess is our Distribution also at IOS. I read the document on this problem and it recommeded disabling igmp snooping on both IOS 6500's but I wanted to see what impact that would impose to our Datacenter Distribution if that was to be disabled and all multicast would then be broadcasted. Any suggestions or precautions to take?
