Xumuc is has the wan links in place to the new locations in the

You are a consultant for being brought in by XUMUC to assist with a merger with another company.

Background:

XUMUC is has the WAN links in place to the new locations in the Houston Region.  XUMUC currently has 2 other Regions San Francisco and Denver.  Originally, XUMUC was only in one region (San Francisco).  The previous consultant did a poor job with the integration resulting in a poor IP address scheme as a result routing tables at the summarization points and at the San Francisco Campus are very large.  In addition, no VLAN structure was developed to isolate broadcast traffic.  There are 4 main departments in XUMC: sales, finance, human resources, and research and development.  Also, there has been some concern that the WAN transport was not able to accommodate the network traffic.  Finally, all addresses in the network are statically assigned resulting in high administration overhead when changes are needed XUMC would like this changed to lower administrative overhead. 

For assigning IP addresses you can assume any one from the following network addresses.

172.16.0.0/16
172.17.0.0/16
172.18.0.0/16
172.19.0.0/16
172.20.0.0/16

or
10.10.0.0/16
10.5.0.0/16
10.6.0.0/16
10.7.0.0/16
10.8.0.0/16
