Description Configure a limit for the number of routes installed in a routing table based upon the
route prefix.
Using a prefix limit, you can curtail the number of prefixes received from a CE router in a
VPN. Prefix limits apply only to dynamic routing protocols and are not applicable to static
or interface routes.
NOTE: The maximum-prefixes statement is similar to the maximum-paths
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).
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
