Abstract:

   The Designated Forwarder concept is leveraged to prevent looping of
   BUM traffic into a tenant network sourced across an NVO fabric for
   multihoming deployments.  [RFC7432] defines a preliminary approach
   to select the DF for an ES, VLAN or ES, VLAN Group, spanning
   multiple NVEs.  [RFC8584] makes the election logic more robust and
   fine grained by inculcating fair election of DF, handling most of
   the prevalent use cases.  This document presents a deployment
   problem and a corresponding solution which cannot be easily
   resolved by rules mentioned in [RFC7432] and [RFC8584].  It
   involves redundant firewall deployment on disparate overlay sites
   connected over WAN.  The requirement is to allow reachability, ONLY,
   to the local firewall, unless there is an outage.  In case of
   outage the reachability can be extended to the remote site's
   firewall over WAN.
