Dear Sir, 

there was some confusion to me while understanding last PKT File You shared, therefore i have again designed a PKT File with inter VLAN with OFSP working (but loopback address isn't given yet). However at next, i want to extend this network up to BGP which i cant do at my own, Coz Am not clear about it. Please guide further about how to do it all with inter VLAN, OSPF and BGP.

As my main idea is to design a proper College Campus plan with Inter VLAN, OSPF and BGP.

You have only 1 MLS switch doing routing for all vlans so no need for any routing protocols.  If you add another router or MLS switch, then enable OSPF with router ospf 1,  network 172.16.0.0 0.0.255.255 area 0  to advertise 3 vlans you have now. Similarly, enable ospf on new device and advertise its networks.

You can put DHCP server box in every vlan and set up pool for it Or connect DHCP server to Main switch and set up 3 pools for all vlans.  I think then you need a ip helper-address x.x.x.x command for those vlans that are not directly connected to network that DHCP server sits on.  Alternatively, you can set new network/subnet for Servers like DHCP, DNS, etc and put your DHCP there serving all vlans again.
