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

Uncommitted changes found, commit them? [yes]: y

RP/0/RSP1/CPU0:Mar 30 18:05:13 : config[65740]: %LIBTARCFG-6-COMMIT : Configuration committed by user 'cisco'. Use 'show configuration commit changes 1000000542' to view the changes.

RP/0/RSP1/CPU0:Mar 30 18:05:13 : config[65740]: %SYS-5-CONFIG_I : Configured from console by cisco

RP/0/RSP1/CPU0:router#

Routing Policy Language Line and Policy Limits

Two limits for Routing Policy Language (RPL) configurations exist:

1.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.

2.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.

The limits for RPL lines and policies are summarized in Table 4-7. You can change the default values up to the absolute maximum, but you cannot change the value to a number less than the number of items that are currently configured.

Table 4-7	Maximum Lines of RPL: Configuration Limits and Commands
		Default	Absolute		Show Current Settings
		Maximum	Maximum	Configuration Command	Command
Limit Description		Limit	Limit	(Global Configuration Mode)	(EXEC Mode)
Maximum number of RPL lines		65,536	131,072	rpl maximum lines n	show rpl maximum lines
Maximum number of RPL policies		3500	5000	rpl maximum policies n	show rpl maximum
					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.

RP/0/RSP1/CPU0:router# show rpl maximum
