I would rather say `tune? than `solve?. Until now I'm confused about the fact that you need a existing default route to use 'ip net-aggregate': "ip net-aggregate - Optimizes the CAM for devices that have very large IP route tables (100,000 or more), where most of those routes use the same next hops as the default route." "CAM network aggregation requires a default route in the IP route table." -- Gerald (ax/tc)
