Changing the Maximum Number of Allowable Static Routes
This task explains how to change the maximum number of allowable static routes.
Restrictions
The number of static routes that can be configured on a router for a given address family is limited by
default to 4000. The limit can be raised or lowered using the maximum path command. Note that if you
use the maximum path command to reduce the configured maximum allowed number of static routes
for a given address family below the number of static routes currently configured, the change is rejected.
In addition, understand the following behavior: If you commit a batch of routes that would, when
grouped, push the number of static routes configured above the maximum allowed, the first n routes in
the batch are accepted. The number previously configured is accepted, and the remainder are rejected.
The n argument is the difference between the maximum number allowed and number previously
configured.
