How to Configure Remote Loop-Free Alternate - Fast Reroute

	Command		Purpose
Step 9	max-lsp-lifetime seconds		Configures the maximum link-state packets (LSPs) lifetime.
			• seconds—Maximum LSP lifetime in seconds. The range is from
	Example:		1 to 65535.
	Router(config-router)#
	max-lsp-lifetime 65535
Step 10	lsp-refresh-interval		Sets the link-state packet (LSP) refresh interval.
	seconds		• seconds—Interval (in seconds) at which LSPs are
	Example:		refreshed.The range is 1 to 65535 seconds. The default value is
			900 seconds (15 minutes).
	Router(config-router)#
	lsp-refresh-interval 900
Step 11	spf-interval [level-1 level-2]		Customizes IS-IS throttling of shortest path first (SPF) calculations.
	spf-max-wait [spf-initial-wait		• level-1—(Optional) Apply intervals to Level-1 areas only.
	spf-second-wait]
			• level-2—(Optional) Apply intervals to Level-2 areas only.
	Example:		• spf-max-wait—Indicates the maximum interval (in seconds)
	Router(config-router)# spf-interval 5		between two consecutive SPF calculations. The range is 1 to
	50	200	120 seconds. The default is 10 seconds.
			• spf-initial-wait—(Optional) Indicates the initial SPF
			calculation delay (in milliseconds) after a topology change. The
			range is 1 to 120000 milliseconds. The default is 5500
			milliseconds (5.5 seconds).
			• spf-second-wait—(Optional) Indicates the hold time between
			the first and second SPF calculation (in milliseconds). The
			range is 1 to 120000 milliseconds. The default is 5500
			milliseconds (5.5 seconds).
Step 12	prc-interval prc-max-wait		Customizes IS-IS throttling of partial route calculations (PRC).
	[prc-initial-wait prc-second-wait]		• prc-max-wait—Indicates the maximum interval (in seconds)
	Example:		between two consecutive PRC calculations. Value range is 1 to
			120 seconds. The default is 5 seconds.
	Router(config-router)# prc-interval 5		• prc-initial-wait—(Optional) Indicates the initial PRC
	50 200
			calculation delay (in milliseconds) after a topology change. The
			range is 1 to 120,000 milliseconds. The default is 2000
			milliseconds.
			• prc-second-wait—(Optional) Indicates the hold time between
			the first and second PRC calculation (in milliseconds). The
			range is 1 to 120,000 milliseconds. The default is 5000
			milliseconds (5 seconds).
