The IESG has approved the following document: - 'TRILL (TRansparent Interconnection of Lots of Links): Address Flush Message' (draft-ietf-trill-address-flush-06.txt) as Proposed Standard This document is the product of the Transparent Interconnection of Lots of Links Working Group. The IESG contact persons are Alvaro Retana, Alia Atlas and Deborah Brungard. A URL of this Internet Draft is: https://datatracker.ietf.org/doc/draft-ietf-trill-address-flush/ Technical Summary The TRILL (TRansparent Interconnection of Lots of Links) protocol, by default, learns end station addresses from observing the data plane. In particular, it learns local MAC addresses and edge switch port of attachment from the receipt of local data frames and learns remote MAC addresses and edge switch of attachment from the decapsulation of remotely sourced TRILL Data packets. This document specifies a message by which a TRILL switch can explicitly request other TRILL switches to flush certain MAC reachability learned through the decapsulation of TRILL Data packets. This is a supplement to the TRILL automatic address forgetting and can assist in achieving more rapid convergence in case of topology or configuration change. Working Group Summary No. This draft is part of a package of directory/ARP services for TRILL. Flushing unused MAC learned MAC addresses is key to keeping the bridge-router function scalable. A late IPR disclosure required a second WG Last Call but caused no concern or contention. Document Quality Huawei has implemented a subset of this protocol.
