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.

Thanks
Saumya,

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.
