A Border Gateway Protocol (BGP)

Status of this Memo

This RFC, together with its companion RFC-1164, "Application of the Border Gateway Protocol in the Internet", 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.
