Autonomic IPv6 Edge Prefix Management in Large-scale Networks
draft-ietf-anima-prefix-management-07
Abstract
This document defines two autonomic technical objectives for IPv6
prefix management at the edge of large-scale ISP networks, with an
extension to support IPv4 prefixes. An important purpose of the
document is to use it for validation of the design of various
components of the autonomic networking infrastructure.
