Abstract
Techniques disclosed herein provide a method for efficiently propagating address resolution reply messages. A first router in a first network receives an address resolution request message from a second router in a second network. The first router generates an entry for the address resolution request message and stores the entry in a pending address resolution requests table. When the first router receives a route advertisement, it extracts a network layer address from the route advertisement and determines whether the pending address resolution requests table includes an entry for the network layer address. If so, the router extracts a link layer address from the route advertisement and generates an address resolution reply message comprising the network layer address and the link layer address. The router then transmits the address resolution reply message to the second router.
