Why is the number of routes in the routing table inconsistent with the number of FIB entries after a required route iteration on an S series switches

Q: Why is the number of routes in the routing table inconsistent with the number of FIB entries after a required route iteration?

A: After routes are iterated as required, routes of multiple outbound interfaces are not generated and there is only one route with multiple outbound interfaces. This route is iterated to multiple routes when delivered to the FIB. As a result, the number of routes in the routing table is inconsistent with the number of FIB entries.
Among the route flags, R indicates that the route is iterated, and D indicates that the route is successfully delivered to the FIB.
