Abstract

The Border Gateway Protocol (BGP), described in RFC 1163, is an interdomain 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 [2].

Application of the Border Gateway Protocol in the Internet

Status of this Memo

This RFC, together with its companion RFC-1163, "A Border Gateway

Protocol (BGP)", define a Proposed Standard for an inter-autonomous

system routing protocol for the Internet.

This protocol, like any other at this initial stage, may undergo

modifications before reaching full Internet Standard status as a

result of deployment experience. Implementers are encouraged to

track the progress of this or any protocol as it moves through the

standardization process, and to report their own experience with the

protocol.

This protocol is being considered by the Interconnectivity Working

Group (IWG) of the Internet Engineering Task Force (IETF).

Information about the progress of BGP can be monitored and/or

reported on the IWG mailing list (IWG@nri.reston.va.us).

Please refer to the latest edition of the "IAB Official Protocol

Standards" RFC for current information on the state and status of

standard Internet protocols.

Distribution of this memo is unlimited.
