1. Introduction
The 6Bone is an IPv6 testbed to assist in the evolution and
deployment of IPv6. Because of this, it is important that the core
backbone of the IPv6 network maintain stability, and that all
operators have a common set of rules and guidelines by which to
deploy IPv6 routing equipment.
This document provides a set of guidelines for all 6bone routing
equipment operators to use as a reference for efficient and stable
deployment of 6bone routing systems. As the complexity of the 6Bone
grows,the adherence to a common set of rules becomes increasingly
important in order for an efficient, scalable backbone to exist.
This document uses BGP-4 with Multiprotocol Extensions for BGP-4 as
defined [RFC 2283], commonly referred to as BGP4+, as the currently
accepted EGP.
The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT",
"SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this
document are to be interpreted as described in [RFC 2119].
