Strategies: Routing and Addressing
Provide documentation regarding routing strategies...cover the customer spectrum from small to large.
Consider an architecture that protects your critical services from misconfigured or leaking routes – critical in a datacenter environment.
Build abstraction layer into your access network where addressing/routing can be “normalized”.
Utilize NAT to retain control of addressing.
Have policy in place regarding the use of private addressing...keep these addressing issues in mind as you design and redesign your network.
