Ip Fib Optimize; Commands For Urpf - Planet SGS-6341 Series Command Manual

19.3 Commands for IP Route Aggregation

19.3.1 ip 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
