Abstract
A system for selectively programming the forwarding hardware of a switch is provided. During operation, the system can operate the switch as a tunnel endpoint of a tunnel in conjunction with a remote switch. The tunnel can facilitate a virtual private network (VPN). The system can determine, using a routing protocol, a set of routes for the VPN. The system can maintain the set of routes in a first data structure in an application space. The set of routes can include a first subset of routes to remote hosts of the VPN and a second subset of routes comprising the rest of the set of routes. The system can program the second subset routes in the forwarding hardware. Upon receiving a packet for a remote host, the system can determine a route to the remote host from the first set of routes and program the route in the forwarding hardware.
