Abstract
This document analyzes the transition to IPv6 in enterprise networks
focusing on IP Layer 3. These networks are characterized as having
multiple internal links and one or more router connections to one or
more Providers, and as being managed by a network operations entity.
The analysis focuses on a base set of transition notational networks
and requirements expanded from a previous document on enterprise
scenarios. Discussion is provided on a focused set of transition
analysis required for the enterprise to transition to IPv6, assuming
a Dual-IP layer (IPv4 and IPv6) network and node environment within
the enterprise. Then, a set of transition mechanisms are recommended
for each notational network.
