Abstract

Methods, Systems, and Virtual Routers are provided for providing dynamic route exchange between routers. First and second routers are configured to communicate route information to one another. When a new route is detected in the first router, it is dynamically communicated to the second router using a lightweight protocol. Both the sending and receiving routers can apply policies to determine whether routes are to be sent or received. In some embodiments, when a network packet is received and associated with a route that was learned, a router uses an interface reference associated with the route, and by activating the reference the network packet is directed to a next address in a network. In this way, a router need not directly learn routes, but rather a reference can be used to activate an interface that knows how to handle a learned route.
