Chapter 39 Remote Loop-Free Alternate - Fast Reroute

How to Configure Remote Loop-Free Alternate - Fast Reroute

	Command	Purpose
Step 13	lsp-gen-interval [level-1 level-2]	Customizes IS-IS throttling of LSP generation.
	lsp-max-wait [lsp-initial-wait	• level-1—(Optional) Apply intervals to Level-1 areas only.
	lsp-second-wait]
		• level-2—(Optional) Apply intervals to Level-2 areas only.
	Example:	• lsp-max-wait—Indicates the maximum interval (in seconds)
	Router(config-router)#	between two consecutive occurrences of an LSP being
	lsp-gen-interval 5 50 200	generated. The range is 1 to 120 seconds. The default is 5
		seconds.
		• lsp-initial-wait—(Optional) Indicates the initial LSP
		generation delay (in milliseconds). The range is 1 to 120,000
		milliseconds. The default is 50 milliseconds.
		• lsp-second-wait—(Optional) Indicates the hold time between
		the first and second LSP generation (in milliseconds). The
		range is 1 to 120,000 milliseconds. The default is 5000
		milliseconds (5 seconds).
Step 14	no hello padding	Reenables IS-IS hello padding at the router level.
	Example:
	Router(config-router)# no hello
	padding
Step 15	log-adjacency-changes	Configures the router to send a syslog message when an OSPF
		neighbor goes up or down.
	Example:
	Router(config-router)#
	log-adjacency-changes
Step 16	fast-reroute per-prefix {level-1	Configures an FRR path that redirects traffic to a remote LFA tunnel
	level-2} {all route-map	for either level 1 or level 2 packets.
	route-map-name}	• level-1—Enables per-prefix FRR of level 1 packets.
	Example:	• level-2—Enables per-prefix FRR of level 2 packets.
	Router(config-router)# fast-reroute	• all—Enables FRR of all primary paths.
	per-prefix level-1 all	• route-map—Specifies the route map for selecting primary
		paths for protection.
		• route-map-name—Route map name.
Step 17	fast-reroute remote-lfa {level-1	Configures an FRR path that redirects traffic to a remote LFA
	level-2} mpls-ldp [maximum-metric	tunnel.
	metric-value]	• level-1—Enables LFA-FRR of level 1 packets.
	Example:	• level-2—Enables LFA-FRR of level 2 packets.
	Router(config-router)# fast-reroute	• mpls-ldp—Specifies that the tunnel type is MPLS or LDP.
	remote-lfa level-1 mpls-ldp	• maximum-metric—(Optional) Specifies the maximum metric
		value required to reach the release node.
		• metric-value—Metric value.
