aggregation algorithm; the “no ip fib optimize” disables the optimized IP route aggregation algorithm.
17.2.2.2IP Route Aggregation Configuration Command
17.2.2.2.1ip fib optimize
Command: ip fib optimize no ip fib optimize
Function: Enables the switch to use optimized IP route aggregation algorithm; the “no ip fib optimize” disables the optimized IP route aggregation algorithm.
Default: Optimized IP route aggregation algorithm is disabled by default.
Command mode: Global Mode
Usage Guide: This command is used to optimize the aggregation algorithm: if the route table contains no default route, the next hop most frequently referred to will be used to construct a virtual default route to simplify the aggregation result. This method has the benefit of more effectively simplifying the aggregation result. However, while adding a virtual default route to the chip segment route table reduces CPU load, it may introduce unnecessary data stream to switches of the next hop. In fact, part of local switch CPU load is transferred to switches of the next hop.
Example: Disabling optimized IP route aggregation algorithm. Switch(Config)# no ip fib optimize
