Label Switched Path Ping and Traceroute Multipath Support for Link Aggregation Group Interfaces
RFC 8611, “Label Switched Path Ping and Traceroute Multipath Support for Link Aggregation Group Interfaces”, is a Proposed Standard document published in June 2019 by N. Akiya, G. Swallow, S. Litkowski, B. Decraene, J. Drake, M. Chen. It updates RFC 8029. It has since been updated by RFC 9041. The canonical text is published by the RFC Editor.
Abstract
This document defines extensions to the MPLS Label Switched Path (LSP) Ping and Traceroute mechanisms as specified in RFC 8029. The extensions allow the MPLS LSP Ping and Traceroute mechanisms to discover and exercise specific paths of Layer 2 (L2) Equal-Cost Multipath (ECMP) over Link Aggregation Group (LAG) interfaces. Additionally, a mechanism is defined to enable the determination of the capabilities supported by a Label Switching Router (LSR).
This document updates RFC 8029.
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.
