Transparent Interconnection of Lots of Links : Interface Addresses APPsub-TLV
RFC 7961, “Transparent Interconnection of Lots of Links : Interface Addresses APPsub-TLV”, is a Proposed Standard document published in August 2016 by D. Eastlake 3rd, L. Yizhou. The canonical text is published by the RFC Editor.
Abstract
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.
What “Proposed Standard” means
An entry-level standards-track specification: stable, peer-reviewed and a solid basis for implementation, though it may still evolve before becoming an Internet Standard.
