Multiple SDN Controller-enabled L3VPN


In this proof-of-concept from the 2016 OPNFV Summit, Georg Kunz, Senior Systems Designer, SDN, Ericsson, demonstrates an L3VPN enabled datacenter with multiple SDN Controllers from different vendors, including:

  • A common OpenStack networking ecosystem, namely Gluon, is used to initiate the establishment of the L3VPN.
  • Multiple Servers are running different vendor controllers & overlay routing software for L3VPN – MPLS VRFs
  • Multi-vendor routers are running in one subnet
  • Common control plane parameters are shared – BGP communities (e.g. Route Targets (RT)) across the multi-vendor controllers
  • Controllers and routers communicate directly without going through any gateway for east-west traffic
