Description
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:
OSPF 10.10.10.0/24 ISIS 10.10.10.0/24
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).
Local and direct routes are not considered as part of
maximum-path and
maximum-prefixes limits.
Options
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.
