one question when setting up mutlicast

[Isaac]

I am setting up multicast on a nexus switch,  I am pretty confident I know what needs to be done, so my question is when setting this up will traffic be affected?

Hi @Isaac ,

When enabling Multicast PIM related commands, I do not expect disruption of Unicast traffic.

Cheers.

To config Multicast PIM - depends on sparse or sparse-dense mode ( do not recommend dense mode at all)

you are ok to do.

unlike IOS, you need enable feature before you config PIM

feature pim to stat with

Thanks for everyone's input on this, will be making the configuration change today.

wanted to provide an update: the configuration worked here is some back ground information. The paging server is on the same vlan as the phones, with that being said all I needed to do was find an IP address I could reserve for ip igmp snooping querier. the complete commands are:

conf t 

     vlan configuration 110

         ip igmp snooping querier (IP address in same subnet)

applied this to both nexus switches and worked.
