Abstract
In general, techniques are described for ensuring the distribution of Virtual Private Network (VPN) routes in a service provider network configured with multiple VPN services. In some examples, a network device receives configuration data that defines a VPN service associated with a route target. The network device, responsive to receiving the configuration data, sends a request for routes that match a type of the VPN service to a routing protocol speaker. The network device receives routes that match the type of the VPN service and are associated with the route target, installs the routes that match the type of the VPN service and are associated with the route target to the routing information base. The network device forwards traffic for the VPN service in accordance with the installed routes.
