(1) What type of RFC is being requested (BCP, Proposed Standard,
Internet Standard, Informational, Experimental, or Historic)? Why
is this the proper type of RFC? Is this type of RFC indicated in the
title page header?
The document specifies two models of EVPN inter-subnet forwarding
with corresponding procedures and encodings, so it needs to be
a standard track document and is properly indicated so in the
title page header.
(2) The IESG approval announcement includes a Document Announcement
Write-Up. Please provide such a Document Announcement Write-Up. Recent
examples can be found in the "Action" announcements for approved
documents. The approval announcement contains the following sections:
EVPN provides an extensible and flexible multi-homing VPN solution
over an MPLS/IP network for intra-subnet connectivity among Tenant
Systems and End Devices that can be physical or virtual. However,
there are scenarios for which there is a need for a dynamic and
efficient inter-subnet connectivity among these Tenant Systems and
End Devices while maintaining the multi-homing capabilities of EVPN.
This document describes an Integrated Routing and Bridging (IRB)
solution based on EVPN to address such requirements.
