Deploying IPv6 in WAN/Branch Networks describes the initial configuration of many aspects of routing for Cisco routers and layer-3 switches. It comes from the book IPv6 for Enterprise Networks published in 2011 and provided courtesy of Cisco Press.

To find documentation for a specific Cisco router or layer-3 switch, go to the documentation page on the Cisco website. Next, click on “All Categories” and select “support”. Next, click on “All Types” and select “Configuration Guides”. Next, click on the “All Products” search window and enter a specific model number. Finally, scroll down the resulting list of documents to the Internetwork Operating System (IOS) document of interest for the specific model number and click on it.

A complete reference with numerous examples and detailed explanations of specific IOS configuration options for all Cisco routers and layer-3 switches is available on the Cisco IOS IPv6 Command Reference page on the Cisco website. An IPv6-specific Frequently Asked Questions (FAQ) file is maintained by Cisco. Cisco in the past maintained an IPv6-specific Knowledge Base and maintains a Small Business Support Community for its equipment.
