Ranjith,
Do you want someone to config the switches for you? That's how it looks.
We told you - enable ipforwarding on VLANs, provide at least static routes on core routers, provide default routes on switches, think of tuning the vlan and addressing scheme. You could be done within an hour with your issue, but you didn't confirm what is your status right now, did you try all those steps and did they work, we have seen just single device config at the beginning.
If it's not enough here for you to work on your case, call GTAC as Drew said.
Regards,
Tomasz
