Status of this Memo
This document specifies an Internet standards track protocol for the
Internet community, and requests discussion and suggestions for
improvements. Please refer to the current edition of the "Internet
Official Protocol Standards" (STD 1) for the standardization state

This document, together with its companion document, "A Border
Gateway Protocol 4 (BGP-4)", define an inter-autonomous system
routing protocol for the Internet. "A Border Gateway Protocol 4
(BGP-4)" defines the BGP protocol specification, and this document

This memo describes the use of the Border Gateway Protocol (BGP) 
in the Internet environment. BGP is an inter-Autonomous System
routing protocol. The network reachability information exchanged via
BGP provides sufficient information to detect routing loops and
enforce routing decisions based on performance preference and policy
constraints as outlined in RFC 1104 . In particular, BGP exchanges
routing information containing full AS paths and enforces routing
