This document discusses Cisco's implementation of IPv6 across its own internal network and services. Some key points include: - Cisco transitioned its global network, data centers, user access systems, and network management to dual-stack IPv6/IPv4 in 2012 after several years of planning and lab testing. - Cisco websites like www.cisco.com and webex.com were converted to IPv6, and began seeing small but growing amounts of IPv6 traffic. - Lessons learned included the need for cross-team collaboration, staff training, and network management tool preparation for IPv6 support. - Cisco's implementation provides an example for other large enterprises transitioning to IPv6 across a global infrastructure
