I request the Chairs and group member to review this draft and provide their valuable comments. This document in addition to its predecessors discourse, also calls out the few additional cases ICMP error propagation from underlay network towards tunnel endpoints and best effort to propagate it to the packet originator in the tenant network.

Name: draft-saum-nvo3-mtu-propagation-over-evpn-overlays Revision: 00 Title: MTU propagation over EVPN Overlays Document date: 2021-08-04 Group: Individual Submission Pages: 32 URL: https://www.ietf.org/archive/id/draft-saum-nvo3-mtu-propagation-over-evpn-overlays-00.txt Status: https://datatracker.ietf.org/doc/draft-saum-nvo3-mtu-propagation-over-evpn-overlays/ Htmlized: https://datatracker.ietf.org/doc/html/draft-saum-nvo3-mtu-propagation-over-evpn-overlays Abstract: Path MTU Discovery between end-host-devices/Virtual-Machines/servers/ workloads connected over an EVPN-Overlay Network in an Datacenter/Campus/enterprise deployment, is a problem, yet to be resolved in the standards forums. It needs a converged solution to ensure optimal usage of network and computational resources of the underlay routers/switches forming the basis of the overlay network. This documents takes leads from the guidelines presented in [RFC4459]. The overlay connectivity can pan across various sites (geographically seperated or collocated) for realizing a Datacenter Interconnect or intersite VPNs between campus sites (buildings, branch offices etc). This literature intends to solve problem of icmp error propagation from an underlay routing/switching device to an end-host (hooked to EVPN overlay), thus facilitating "accurate MTU" learnings. This document also leverages the icmp multipart message extension, mentioned in [RFC4884] to carry the original packet in the icmp PDU.
