This document provides guidance for those procuring network equipment, by identifying functions that are essential to the proper functioning of equipment in a Government of Canada IPv6 environment (see the Technical Requirements for Internet Protocol Version 6 Network Equipment Procurement Guideline). A list of base functions that applies to all network equipment is followed by lists of functions that apply to the equipment when used in specific situations. Following these is a section that addresses future needs, also organized according to the network scenario in which the equipment will be used.

When preparing network equipment requirements, buyers should include the IPv6 functions referred to above, as specified in the Technical Requirements for Internet Protocol Version 6 Network Equipment Procurement Guideline.

It is possible that not all functions listed are currently supported by all vendors and that some of the quoted Internet standards may be updated or become obsolete. As a result, a "best fit" may be required when equipment must be replaced due to end-of-life or other considerations, and cannot wait for the availability of the full IPv6 functionality recommended in this guideline.
