Description

Assign a FIB install priority, as high or low, for matching routes. Non-matching routes are by default classified as unprioritized. When the routes are installed in the forwarding table, the number of forwarding table entries that routes of a particular priority get depends on the memory percentage allotted for the priority. Refer fib-prioritization to read more.

Issue the run show route <prefix> extensive command as shown in the following example to view the FIB install priority of a particular route.
