Suppose that Internetrouting in the US used geographical routing, and the first 12 bitsof every IP address represent a geographical area similar in sizeto a telephone area code. Megacorp gets the prefix 188.8.131.52/16,based geographically in Chicago, and allocates subnets from thisprefix to its offices in all 50 states. Megacorp routes all itsinternal traffic over its own network.
(a). Assuming all Megacorp traffic must enter and exit inChicago, what is the route of traffic to and from the San Diegooffice to a client also in San Diego?
(b). Now suppose each office has its own link to a local ISP,but still uses its 184.108.40.206/16 IP addresses. Now what is the routeof traffic between the San Diego office and its neighbor?
(c). Suppose Megacorp gives up and gets a separate geographicalprefix for each office, eg 220.127.116.11/24 for San Diego and18.104.22.168/24 for Boston. How must it configure its internal IPforwarding tables to ensure that its internal traffic is stillrouted entirely over its own network?
