Configuring Additional Router Features
Number of Parallel Links (max-paths): Example
In the following example, the maximum paths command is used to set the maximum number of parallel
routes:
RP/0/RSP1/CPU0:router# configure
RP/0/RSP1/CPU0:router(config)# router ospf 100
RP/0/RSP1/CPU0:router(config-router)# maximum paths 10
RP/0/RSP1/CPU0:router(config-router)# end

Routing Policy Language Line and Policy Limits
Two limits for Routing Policy Language (RPL) configurations exist:
1.
2.
The limits for RPL lines and policies are summarized in
to the absolute maximum, but you cannot change the value to a number less than the number of items
that are currently configured.

Maximum number of RPL lines
Maximum number of RPL policies
Examples
In the following example, the show rpl maximum command is used in EXEC mode to display the
current setting for RPL limits and number of each limit currently in use. A summary of the memory used
by all of the defined policies is also shown below the limit settings.

Number of RPL lines: The number of configuration lines entered by the user, including the
beginning and ending statements (that is "route-policy"). The number of configuration lines for sets
is also included.
Number of RPL policies: The number of policies that can be configured on the router. Policies are
counted only once: Multiple use of the same policy counts as a single policy toward the limit 1.
