How to Configure Remote Loop-Free Alternate - Fast Reroute

	Command	Purpose
Step 5	service instance id ethernet	Configures an Ethernet service instance on an interface.
		• id—Integer that uniquely identifies a service instance on an
	Example:	interface.
	Router(config-if)# service instance 7
	ethernet
Step 6	encapsulation dot1q vlan-id	Enables IEEE 802.1Q encapsulation of traffic on a specified
		interface in a VLAN.
	Example:	• vlan-id—Virtual LAN identifier.
	Router(config-if)# encapsulation dot1q
	7
Step 7	rewrite ingress tag pop 1 symmetric	Specifies the encapsulation adjustment to be performed on a frame
		ingressing a service instance.
	Example:	• pop—Removes a tag from a packet.
	Router(config-if)# rewrite ingress tag	• 1—Specifies the outermost tag for removal from a packet.
	pop 1 symmetric
		• symmetric—Indicates a reciprocal adjustment to be done in the
		egress direction. For example, if the ingress pops a tag, the
		egress pushes a tag and if the ingress pushes a tag, the egress
		pops a tag.
Step 8	bridge-domainbridge-domain-id	Enables RFC 1483 ATM bridging or RFC 1490 Frame Relay
		bridging to map a bridged VLAN to an ATM permanent virtual
	Example:	circuit (PVC) or Frame Relay data-link connection identifier
		(DLCI).
	Router(config-if)# bridge-domain 7
		• bridge-domain-id—Bridge domain identifier.
Step 9	interface vlan bridge-domain-id	Configures an Ethernet interface to create or access a dynamic SVI.
	Example:
	Router(config-if)# interface vlan 7
Step 10	ip address ip-address	Specifies an IP address for the specified interface.
	Example:
	Router(config-if)# ip address 7.7.7.1
	255.255.255.0
Step 11	exit	Exits the interface configuration mode and enters the global
		configuration mode.
	Example:
	Router(config-if)# exit
Step 12	router ospf	Enables the OSPF routing protocol and enters the router
		configuration mode.
	Example:
	Router(config)# router ospf
