A new Request for Comments is now available in online RFC libraries. RFC 7961 Title: Transparent Interconnection of Lots of Links (TRILL): Interface Addresses APPsub-TLV Author: D. Eastlake 3rd, L. Yizhou Status: Standards Track Stream: IETF Date: August 2016 Mailbox: d3e3e3@gmail.com, liyizhou@huawei.com Pages: 24 Characters: 50012 Updates/Obsoletes/SeeAlso: None I-D Tag: draft-ietf-trill-ia-appsubtlv-09.txt URL: https://www.rfc-editor.org/info/rfc7961 DOI: http://dx.doi.org/10.17487/RFC7961 This document specifies a TRILL (Transparent Interconnection of Lots of Links) IS-IS application sub-TLV that enables the reporting by a TRILL switch of sets of addresses. Each set of addresses reports all of the addresses that designate the same interface (port) and also reports the TRILL switch by which that interface is reachable. For example, a 48-bit MAC (Media Access Control) address, IPv4 address, and IPv6 address can be reported as all corresponding to the same interface reachable by a particular TRILL switch. Such information could be used in some cases to synthesize responses to, or bypass the need for, the Address Resolution Protocol (ARP), the IPv6 Neighbor Discovery (ND) protocol, or the flooding of unknown MAC addresses. This document is a product of the Transparent Interconnection of Lots of Links Working Group of the IETF. This is now a Proposed Standard. STANDARDS TRACK: This document specifies an Internet Standards Track protocol for the Internet community, and requests discussion and suggestions for improvements.
