Enabling High Availability Features

Setting the Config-Register Boot Variable

Though it is not required, we recommend that you modify the software configuration register boot field so that the system boots the same image that the hw-module slot slot-numberimage file-speccommand specifies in the “Configuring RPR and RPR+” section on page 46 .

	Command	Purpose
Step 1
	Router# show version	Obtains the current configuration register setting.
Step 2
	Router# configure terminal	Enters global configuration mode.
Step 3
	Router(config)# boot system flash	Specifies the filename of an image stored in Flash
	slotslot-number:[imagename]	memory.
		• imagename—It is recommended that you set the
		boot variable so that the system boots the same
		image specified by the hw-module slot
		slot-number image file-spec command. See
		Step 2 of the “Configuring RPR and RPR+”
		section on page 46.
		• slot-number—Specifies the active RSP slot
		where the Flash memory card or Flash Disk is
		located. Valid numbers are slot 2 or slot 3 for a
		Cisco 7507 router and slot 6 or slot 7 for a
		Cisco 7513 router.
Step 4
	Router(config)# config-registervalue	Modifies the existing configuration register setting
		to reflect the way in which you want to load a system
		image.
		value—0x0 to 0xFFFFFFFF
Step 5
	Router(config)# end	Exits global configuration mode and returns you to
		privileged EXEC configuration mode.
Step 6
	Router# reload	Resets the router with the new configuration
		information.

Configuring RPR and RPR+

Note Online removal of the active RSP causes all line cards to reset and reload, which is the equivalent to an RPR switchover, and results in a longer switchover time. When it is necessary to remove the active RSP from the system, first issue a switchover command to switch from the active RSP to the standby RSP.
