[bess] Notification of new bess-related ID for discussion

[Aaron Bamberger <[e-mail]>]

Hello all,

I had assumed an automated notification for this would have been generated
on the bess mailing list when it was submitted to the datatracker as it's
targeted at this group, but that apparently didn't happen.  I wanted to
post here just to bring folk's attention to and invite discussion of this
draft.

Title           : IMET Route Filtering for Ethernet VPN (EVPN) Ethernet
Tree (E-Tree) with

Abstract:
   RFC 8317 defines EVPN Ethernet Tree (E-Tree) and associated filtering
   rules for both known unicast and broadcast, unknown unicast, and
   multicast (BUM) traffic, using Multiprotocol Label Switching (MPLS)
   encapsulation.  The processes and protocols specified in RFC 8317 for
   performing E-Tree filtering on known unicast traffic are implemented
   entirely with EVPN routes, and are thus also applicable to networks
   using Virtual Extensible LAN (VXLAN) encapsulation.  However, E-Tree
   filtering for BUM traffic is accomplished using specific features of
   MPLS encapsulation, and is thus not applicable for networks using
   VXLAN encapsulation.

   In networks where E-Tree root/leaf role classification is done per-
   provider edge (PE) device, or per-attachment circuit (AC) on each PE
   device, an extension to EVPN type-3 inclusive multicast (IMET) routes
   can be added to allow E-Tree filtering for BUM traffic in networks
   using VXLAN encapsulation.  Additionally, this proposal specifies
   filtering BUM traffic on ingress, as opposed to the egress filtering
   specified by RFC 8317, which can be considered to be more optimal, as
   it reduces the amount of unnecessary BUM traffic transmitted over the
   network.
