Release Information

Statement introduced in JUNOS Release 8.0.

Statement introduced in JUNOS Release 9.0 for EX Series switches.


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


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 warning. You can configure a percentage of the path-limit value that starts triggering the warnings.

Range: 1 through 100

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