Chapter 21 Configuring Pseudowire

Configuring Pseudowire

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
	interface GigabitEthernetslot/port	Specifies an interface to configure.
	Example:
	Router(config)# interface
	GigabitEthernet0/2
Step 4
	service instance instance-number	Configures a service instance and enters the service instance
	ethernet	configuration mode.
	Example:
	Router(config-if)# service instance
	101 ethernet
Step 5
	encapsulation dot1q	Configures encapsulation type for the service instance.
	encapsulation-type
	Example:
	Router(config-if-srv)#
	encapsulation dot1q 101
Step 6
	rewrite ingress tag pop 1 symmetric	Specifies the encapsulation modification to occur on packets at ingress as
		follows:
	Example:	• pop 1—Pop (remove) the outermost tag.
	Router(config-if-srv)# rewrite	• symmetric—Configure the packet to undergo the reverse of the
	ingress tag pop 1 symmetric
			ingress action at egress. If a tag is popped at ingress, it is pushed
			(added) at egress.
		Note	Although the symmetric keyword appears to be optional, you
			must enter it for rewrite to function correctly.
Step 7
	xconnect ip-addressencapsulation	Binds the VLAN attachment circuit to an Any Transport over MPLS
	mpls	(AToM) pseudowire for EoMPLS.
	Example:
	Router(config-if-srv)# xconnect
	11.205.1.1 141 encapsulation mpls
Step 8
	end	Returns to privileged EXEC mode.
	Example:
	Router(config-if-srv)# end
