Description

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

Options

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

Range: 5 through 86,400

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

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

Range: 1 through 4,294,967,295

Default: No default

threshold value—(Optional) Percentage of the maximum number of prefixes that starts triggering warning. You can configure a percentage of the prefix-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 prefix-limit value, then additional routes are rejected.
