Abstract:

   EVPN Integrated Routing and Bridging (IRB) fabrics provide a flexible
   and extensible method for Layer-2 and Layer-3 overlay network
   connectivity.  [EVPN-IRB] defines operation for symmetric and
   asymmetric EVPN IRB using distributed anycast gateway architecture
   (DAG).  In a DAG architecture, both bridging and first-hop routing
   functions for overlay subnets are located on leaf PEs, with first-hop
   routing provided by a distributed anycast gateway provisioned across
   the leaf PEs.  This document describes an architecture and operation
   for EVPN Centralized Anycast Gateway (CAG), which allows the first-
   hop routing function for overlay subnets to be centralized on
   designated IRB GWs while the bridging function is still located on
   the leaf PEs.  The documents also covers trade-offs of deploying a
   CAG as compared with DAG.  It further describes operation for inter-
   op between CAG and DAG based EVPN-IRB network overlays.
