Hierarchy Level


Configure a limit for the number of routes installed in a routing table based upon the route path.


The maximum-paths statement is similar to the maximum-prefixes statement. The maximum-prefixes statement limits the number of unique destinations in a routing instance. For example, suppose a routing instance has the following routes:

These are two routes, but only one destination (prefix). The maximum-paths limit applies the total number of routes (two). The maximum-prefixes limit applies to the total number of unique prefixes (one).


log-interval seconds—(Optional) Minimum time interval (in seconds) between log messages.

  • Range: 5 through 86,400

log-only—(Optional) Sets the route limit as an advisory limit. An advisory limit triggers only a warning, and additional routes are not rejected.

path-limit—Maximum number of routes. If this limit is reached, a warning is triggered and additional routes are rejected.

  • Range: 1 through 4,294,967,295 (232 – 1)

  • Default: No default

threshold value—(Optional) Percentage of the maximum number of routes that starts triggering a warning. You can configure a percentage of the path-limit value that starts triggering the warnings.

  • Range: 1 through 100


When the number of routes reaches the threshold value, routes are still installed into the routing table while warning messages are sent. When the number of routes reaches the path-limit value, then additional routes are rejected.
