Chapter 34 MPLS Traffic Engineering - Fast Reroute Link Protection

How to Configure Traffic Engineering - Fast Reroute Link Protection

DETAILED STEPS

	Command	Purpose
Step 1	enable	Enables privileged EXEC mode.
		• Enter your password if prompted.
	Example:
	Router> enable
Step 2	configure terminal	Enters global configuration mode.
	Example:
	Router# configure terminal
Step 3	mpls traffic-eng auto-tunnel primary	Creates primary tunnels to all the next hops automatically.
	onehop
	Example:
	Router(config)# mpls traffic-eng
	auto-tunnel primary onehop
Step 4	mpls traffic-eng auto-tunnel primary	Configures the range of tunnel interface numbers for primary
	tunnel-num [min min-num] [max max-num]	autotunnels.
	Example:	• min-num—(Optional) Minimum number of the primary tunnels.
		The range is 0 to 65535, with a default value of 65436.
	Router(config)# mpls traffic-eng	• max-num—(Optional) Maximum number of the primary
	auto-tunnel primary tunnel-num min 3
	max 400	tunnels. The max number is the minimum number plus 99. The
		range is from 0 to 65535.
Step 5	mpls traffic-eng auto-tunnel primary	Enables IP processing without an explicit address.
	config unnumbered interface	• interface—Interface on which IP processing is enabled without
	Example:	an explicit address.
	Router(config)# mpls traffic-eng
	auto-tunnel primary config
	unnumbered-interface Loopback102
Step 6	mpls traffic-eng auto-tunnel primary	Configures the period after a failure to remove primary autotunnels.
	timers removal rerouted sec	• sec—Number of seconds after a failure that primary
	Example:	autotunnels are removed. The range is from 30 to 604,800, with
		a default of 0.
	Router(config)# mpls traffic-eng
	auto-tunnel primary timers removal
	rerouted 604800
Step 7	mpls traffic-eng auto-tunnel primary	Enables Label Distribution Protocol (LDP) on primary autotunnels.
	config mpls ip
	Example:
	Router(config)# mpls traffic-eng
	auto-tunnel primary config mpls ip
