The IESG has received a request from the BGP Enabled ServiceS WG (bess) to consider the following document: - 'Operational Aspects of Proxy-ARP/ND in EVPN Networks' <draft-ietf-bess-evpn-proxy-arp-nd-09.txt> as Informational RFC
The IESG plans to make a decision in the next few weeks, and solicits final comments on this action. Please send substantive comments to the last-c...@ietf.org mailing lists by 2020-12-15. Exceptionally, comments may be sent to i...@ietf.org instead. In either case, please retain the beginning of the Subject line to allow automated sorting. Abstract The EVPN MAC/IP Advertisement route can optionally carry IPv4 and IPv6 addresses associated with a MAC address. Remote PEs importing those routes in the same Broadcast Domain (BD) can use this information to reply locally (act as proxy) to IPv4 ARP requests and IPv6 Neighbor Solicitation messages (or 'unicast-forward' them to the owner of the MAC) and reduce/suppress the flooding produced by the Address Resolution procedure. This EVPN capability is extremely useful in Internet Exchange Points (IXPs) and Data Centers (DCs) with large BDs, where the amount of ARP/ND flooded traffic causes issues on connected routers and CEs. This document describes the EVPN Proxy-ARP/ND function augmented by the capability of the ARP/ND Extended Community, which together help IXPs and other operators to deal with the issues derived from Address Resolution in large BDs. The file can be obtained via https://datatracker.ietf.org/doc/draft-ietf-bess-evpn-proxy-arp-nd/ No IPR declarations have been submitted directly on this I-D. _______________________________________________ BESS mailing list BESS@ietf.org https://www.ietf.org/mailman/listinfo/bess
