Internet Engineering Task Force (IETF) H. Zhai Request for Comments: 7357 F. Hu Updates: 6325 ZTE Category: Standards Track R. Perlman ISSN: 2070-1721 Intel Labs D. Eastlake 3rd Huawei O. Stokes Extreme Networks September 2014 Transparent Interconnection of Lots of Links (TRILL): End Station Address Distribution Information (ESADI) Protocol Abstract The IETF TRILL (Transparent Interconnection of Lots of Links) protocol provides least-cost pair-wise data forwarding without configuration in multi-hop networks with arbitrary topologies and link technologies. TRILL supports multipathing of both unicast and multicast traffic. Devices that implement the TRILL protocol are called TRILL switches or RBridges (Routing Bridges). ESADI (End Station Address Distribution Information) is an optional protocol by which a TRILL switch can communicate, in a Data Label (VLAN or fine-grained label) scoped way, end station address and reachability information to TRILL switches participating in ESADI for the relevant Data Label. This document updates RFC 6325, specifically the documentation of the ESADI protocol, and is not backwards compatible. Status of This Memo This is an Internet Standards Track document. This document is a product of the Internet Engineering Task Force (IETF). It represents the consensus of the IETF community. It has received public review and has been approved for publication by the Internet Engineering Steering Group (IESG). Further information on Internet Standards is available in Section 2 of RFC 5741.
