Abstract:
Techniques are presented to stitch existing virtual private networks (VPNs), such as MPLS based VPNs, with virtual private clouds (VPCs) in public cloud data centers. The stitching architecture can be realized by configuring a virtual routing application (VRA) in the VPCs and configuring virtual routing applications and a virtual routing application controller in the existing VPN. For VPCs in public clouds that do not have a VRA, traffic can be default routed to VPCs with a VRA.
