MANAGING AND PROVISIONING VIRTUAL ROUTERS

Methods and systems are provided for provisioning and managing network-based virtual private networks (VPNs). According to one embodiment, routing information, including virtual private network (VPN) addresses reachable, for customer sites connected via service processing switches is learned or discovered. The routing information is disseminated among routers associated with multiple network-based customer VPNs for multiple customers. A routing configuration is generated for a network-based customer VPN based on the routing information and a global customer routing profile. Virtual routers (VRs) of the service processing switches are provisioned to support the customer VPN based on the routing configuration. A custom routing profile for the customer VPN is received that identifies one or more routing protocols to be used for one or more segments of the customer VPN. The customer VPN is automatically reconfigured by programmatically generating appropriate routing configurations for the VRs based on the routing information and the custom routing profile.
