Can you first check that the multicast application is setting the TTL > 1. This is nothing to do with the switch it is a setting on the server itself.

Ajith,

I see some configuration needs to be corrected in your template. The HSRP VIP Address is on different subnet than Vlan 32 INterface IP address, You wont be able to have HSRP successful here after all, and you are using this as an RP address. Your configuration will fail with sparse Mode multicasting and it will revert to Dense Mode since you have sparse-dense configured.

However, with dense Mode, it should work if you have the source setting the ttl for example more than 1 as indicated by Jon.

Please check it out and come back if you need further assistance,
