Advertising Layer 2 Bundle Member Link Attributes in IS-IS
RFC 8668, “Advertising Layer 2 Bundle Member Link Attributes in IS-IS”, is a Proposed Standard document published in December 2019 by L. Ginsberg, A. Bashandy, C. Filsfils, M. Nanduri, E. Aries. The canonical text is published by the RFC Editor.
Abstract
There are deployments where the Layer 3 interface on which IS-IS operates is a Layer 2 interface bundle. Existing IS-IS advertisements only support advertising link attributes of the Layer 3 interface. If entities external to IS-IS wish to control traffic flows on the individual physical links that comprise the Layer 2 interface bundle, link attribute information about the bundle members is required.
This document introduces the ability for IS-IS to advertise the link attributes of Layer 2 (L2) Bundle Members.
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.
