Step 5The CP Hotels web site is being moved to a pair of collocation facilities, each ofwhich will connect back to the data centers via DS-3 links. Taking the existingtopology and routing into account, what do you recommend as the best way toconnect the collocation facility back into the data center?Activity VerificationSome specific things to consider:— Where should the connections terminate in a router?— Assume the collocated routers and firewalls and servers will be managed by CPHotels. If the collocation provider were providing a managed firewalls service, thenCP Hotels might feel the need to put firewalls in at the point where the collocationlinks terminate. We will keep things simple for this Case Study.Your group has completed this activity when you have completed answers to the abovequestions, and selected a presenter for the group.The presenter should be prepared to explain and defend your answers to the class. The topicsfor discussion include the following:• The pros and cons of the current IP addressing scheme, and your proposed changes to theIP addressing scheme.• The pros and cons of the current IP routing scheme, including summarization. And yourproposed improvements or changes to the routing scheme, including summarization.• The pros and cons of the current default routing and redistribution schemes, and yourproposed changes or improvements to the default routing and route redistribution schemes.• Your proposed new addressing scheme to provide out-of-band NAC roles and voiceVLANs in the four HQ buildings.• Your list of key points concerning the impact of moving web servers to collocationfacilities. Your proposed design for how to best connect the collocation facilities back tothe data centers, and how to best perform routing to them.Page 20 WHAT IS MY NAME? (ARCH) v2.0 © 2007 Cisco Systems, Inc.
