Abstract: Technologies are provided for expanding computer network route advertisements. A route expansion server can be configured to receive route advertisements from a router, generate an expanded route advertisement that includes additional network route information, and transmit the expanded route advertisement to another router. The route expansion server can receive a route advertisement from a network zone edge router, comprising a network address prefix. The route expansion server can look up one or more additional network address prefixes associated with the edge router and generate an expanded route advertisement message that indicates that the edge router is a potential next hop for the network address prefix and the one or more additional network address prefixes. The route expansion server can transmit the expanded route advertisement message to another router. In at least some embodiments, the route expansion server can generate different expanded route advertisement messages for different routers.
