Hi,

Source is IP TV connected in Access Switch Cisco 2960x and Destination is their server connected to Nexus 9000.

Thanks

Kamlesh

are they in same vlan?

Hi,

yes it is in same vlan.

Thanks

Kamlesh

whatever you have should be enough, provided there is an ip address present in N9k to act as querier.

Yes, they are providing some IP address for servers.

Thanks

Kamlesh

Hi Furose,

If multicast source & destination is in different VLAN, then what would be recommended config.

Thanks

Kamlesh

with this simple setup, you would have to enable "IP PIM sparse-mode" in both the Vlans' SVI, configure a RP on the same device (N9k).

Thanks Furose,

What would be the access switch configuration, is it

ip igmp snooping vlan vlan-id

or igmp ver 3 required

Thanks

Kamlesh

Hi Kamlesh,

no config is required on the access switch. IGMP snooping is enabled by default and you dont need IGMP v3 here (unless you are using Source-specific multicasting in your network)

Thanks Furose,

I will do configuration and will update you.

Thanks

Kamlesh

Thanks Furose,

It is working.

Thanks

Kamlesh

Hi Furose,

IP TV is working perfect when connect to Core switch but when connecting access switch, quality is degrade. Access switch showing output is :

Do we require any other configuration in Access switches.
