Software defined networking between virtualized entities of a data center and external entities

Abstract:

Techniques are disclosed for providing an inter-autonomous system (inter-AS) service between virtualized entities of one autonomous system with external entities of a different autonomous system. For example, a controller (e.g., software defined networking (SDN) controller) may provide multi-hop exterior Border Gateway Protocol (eBGP) redistribution of virtual private networking (VPN) labels between endpoints of different autonomous systems, otherwise referred to as "inter-AS option C." As described in this disclosure, the SDN controller may facilitate the exchange of appropriate routing labels between endpoints of different autonomous systems to enable forwarding of traffic between the different autonomous systems.
