Case Study: Implement Dial on Demand Routing (DDR) using Cisco Packet Tracer.
 
This case study should describe the use of DDR to connect a worldwide network that consists of a 
central site located in Mumbai and remote sites located in Chennai, Bangalore, and Hyderabad. The 
following scenarios should be considered:
