1. A method, comprising:
- determining, at a network device, a set of routes to one or more reachable addresses in a computer network;
determining a set of no-routes to one or more non-reachable addresses in the computer network;
aggregating the routes and no-routes into one or more reachable route prefixes within which being one or more corresponding non-reachable no-route prefix exceptions; and
utilizing the route prefixes and no-route prefix exceptions.

Abstract
In one embodiment, a network device determines a set of routes to one or more reachable addresses and also a set of no-routes to one or more non-reachable addresses in a computer network. The routes and no-routes may then be aggregated into one or more reachable route prefixes with one or more corresponding non-reachable no-route prefix exceptions. As such, the aggregated combination of route prefixes and no-route prefix exceptions may be utilized by the network device.
