BGP Usage for SDWAN Overlay Networks
draft-dunbar-bess-bgp-sdwan-usage-07
Abstract
The document describes three distinct SDWAN scenarios and discusses
the applicability of BGP for each of those scenarios. The goal of
the document is to demonstrate how BGP-based control plane is used
for large scale SDWAN overlay networks with little manual
intervention.
SDWAN edge nodes are commonly interconnected by multiple underlay
networks which can be owned and managed by different network
providers.
