The IESG has approved the Internet-Drafts: o "A Border Gateway Protocol 4 (BGP-4)" <draft-ietf-bgp-bgp4-10.txt> o "Definitions of Managed Objects for the Fourth Version of Border Gateway Protocol (BGP-4)" <draft-ietf-bgp-mibv4-06.txt> o "Application of the Border Gateway Protocol in the Internet" <draft-ietf-bgp-application-04.txt> as Proposed Standards. In addition, the IESG recommends to the RFC Editor that: o "BGP-4 protocol document roadmap and implementation experience" <draft-ietf-bgp-bgp4-implement-01.txt> be published as an Informational RFC. These four documents are the product of the Border Gateway Protocol Working Group. The IESG contact person is Joel Halpern. Technical Summary This collection of documents describes the newest version of the BGP inter-domain routing protocol (BGP-4). The roadmap and implementation experience document is being advanced as an informational companion to the other documents. BGP-4 is a revision of the current Border Gateway Protocol, previously revision 3. The new revision fixes some minor problems that were found during deployment of BGP-3. The primary changes between BGP-3 and -4 were to enhance the protocol messages, and mechanisms to provide the support needed to deploy CIDR. Correspondingly, the MIB has been revised to correctly reflect the behavior of the protocol. As before, the hooks for reflecting user policy are not part of the MIB. The application statement describes how and where to use BGP. In particular, the document describes the aggregation behavior of BGP-4 in detail. It gives the rules for when aggregation is safe, and how it can be used. This defines the parameters for proper operation of the protocol in support of CIDR. The usage of the policy and path related aspects and elements of BGP is also described. The roadmap and implementation experience document shows that four independent implementations have been built and interoperability tested. Working Group Summary The document reflects extensive discussion within the working group. They also reflect the implementation experience which has been gained with these protocols. Protocol Quality These protocols are extensions of extensively implemented and reviewed protocols. BGP-2 was reviewed by a large team of routing experts. There have been significant changes since then. BGP-3 has been widely deployed. BGP-4 has been reviewed by the working group and the area director.
