Aggregate routesandgenerated routesare used to create summarized routes in Junos, but they behave differently in terms of forwarding.
Step-by-Step Breakdown:
* Aggregate Routes:
* Anaggregate routesummarizes a set of more specific routes, but it does not have a direct forwarding next hop. Instead, it points to the more specific routes for actual packet forwarding.
* Generated Routes:
* Agenerated routealso summarizes specific routes, but it has aforwarding next hopthat is determined based on the availability of contributing routes. The generated route can be used to directly forward traffic.
Juniper Reference:
* Aggregate and Generated Routes: In Junos, aggregate routes rely on more specific routes for forwarding, while generated routes can forward traffic directly based on their next-hop information.
