A method comprising: identifying, by an identification module, a Routing Information Base, RIB, that includes a set of routes that define paths to destinations both inside and outside a network; and creating, by a creation module, a Forwarding Information Base, FIB, that includes a subset of active routes whose total size is below a size threshold by: identifying a policy that defines which routes within the RIB to import into the FIB; creating the FIB based at least in part on the policy, including: importing, from the set of routes within the RIB into the FIB: all internal routes that define paths to destinations inside the network, based on the policy; high-traffic external routes that define paths to destinations outside the network that are receiving amounts of traffic that exceed a traffic threshold; and a default route that defines a path to a default node that facilitates resolution of traffic that does not match any of the internal or high-traffic external routes; and excluding, from the FIB, low-traffic external routes that define paths to destinations outside the network that do not receive amounts of traffic that exceed the traffic threshold. identifying, by an identification module, a Routing Information Base, RIB, that includes a set of routes that define paths to destinations both inside and outside a network; and creating, by a creation module, a Forwarding Information Base, FIB, that includes a subset of active routes whose total size is below a size threshold by: identifying a policy that defines which routes within the RIB to import into the FIB; creating the FIB based at least in part on the policy, including: importing, from the set of routes within the RIB into the FIB: all internal routes that define paths to destinations inside the network, based on the policy; high-traffic external routes that define paths to destinations outside the network that are receiving amounts of traffic that exceed a traffic threshold; and a default route that defines a path to a default node that facilitates resolution of traffic that does not match any of the internal or high-traffic external routes; and excluding, from the FIB, low-traffic external routes that define paths to destinations outside the network that do not receive amounts of traffic that exceed the traffic threshold. identifying a policy that defines which routes within the RIB to import into the FIB; creating the FIB based at least in part on the policy, including: importing, from the set of routes within the RIB into the FIB: all internal routes that define paths to destinations inside the network, based on the policy; high-traffic external routes that define paths to destinations outside the network that are receiving amounts of traffic that exceed a traffic threshold; and a default route that defines a path to a default node that facilitates resolution of traffic that does not match any of the internal or high-traffic external routes; and excluding, from the FIB, low-traffic external routes that define paths to destinations outside the network that do not receive amounts of traffic that exceed the traffic threshold. importing, from the set of routes within the RIB into the FIB: all internal routes that define paths to destinations inside the network, based on the policy; high-traffic external routes that define paths to destinations outside the network that are receiving amounts of traffic that exceed a traffic threshold; and a default route that defines a path to a default node that facilitates resolution of traffic that does not match any of the internal or high-traffic external routes; and all internal routes that define paths to destinations inside the network, based on the policy; high-traffic external routes that define paths to destinations outside the network that are receiving amounts of traffic that exceed a traffic threshold; and a default route that defines a path to a default node that facilitates resolution of traffic that does not match any of the internal or high-traffic external routes; and excluding, from the FIB, low-traffic external routes that define paths to destinations outside the network that do not receive amounts of traffic that exceed the traffic threshold.
