How to Configure MPLS VPNs over IP Tunnels

	Command or Action	Purpose
Step 3
	maximum path ipv4 1-140000	Enters the maximum number of static ipv4 paths that can be
		configured.
	Example:
	RP/0/RP0/CPU0:router (config-static)# maximum
	path ipv4 1-140000
Step 4
	maximum path ipv6 1-140000	Enters the maximum number of static ipv6 paths that can be
		configured.
	Example:
	RP/0/RP0/CPU0:router(config-static)# maximum
	path ipv6 1-140000
Step 5
	end	Saves configuration changes.
	or	• When you issue the end command, the system prompts
	commit	you to commit changes:
		Uncommitted changes found, commit them before
	Example:	exiting(yes/no/cancel)?
	RP/0/RP0/CPU0:router(config-static)# end	[cancel]:
	or	– Entering yes saves configuration changes to the
	RP/0/RP0/CPU0:router(config-static)# commit
		running configuration file, exits the configuration
		session, and returns the router to EXEC mode.
		– Entering no exits the configuration session and
		returns the router to EXEC mode without
		committing the configuration changes.
		– Entering cancel leaves the router in the current
		configuration session without exiting or
		committing the configuration changes.
		• Use the commit command to save the configuration
		changes to the running configuration file and remain
		within the configuration session.
