Chapter 21 Configuring Pseudowire

Configuring L2VPN Pseudowire Redundancy

	Command	Purpose
Step 4
	framing {sf esf}	Selects the T1 framing type.
	Example:
	Router(config-controller)# framing
	esf
Step 5
	exit	Exits the controller configuration mode.
	Example:
	Router(config-controller)# exit
Step 6
	interface cemslot/port	Configures the pseudowire interface to use for the new pseudowire class.
	Example:
	Router(config)# interface cem0/0
Step 7
	cem group-number	Configures the pseudowire interface to use for the new pseudowire class.
	Example:
	Router(config-if)# cem 0
Step 8
	xconnect peer-router-id vcid	Configures a pseudowire to transport TDM data from the CEM circuit
	{encapsulation mpls pw-class	across the MPLS network.
	pw-class-name}	• peer-router-idis the IP address of the remote PE peer router.
	Example:	• vcid is a 32-bit identifier to assign to the pseudowire. The same vcid
		must be used for both ends of the pseudowire.
	xconnect 10.10.10.11 344
	encapsulation mpls	• encapsulation mpls sets MPLS for tunneling mode.
		• pw-class-namespecifies a pseudowire class that includes the
		encapsulation mpls command.
		Note The peer-router-id and vcid combination must be unique on the
		router.
Step 9
	backup peer peer-router-ip-address	Specifies a redundant peer for the pseudowire VC.
	vcid [pw-classpw-class-name]	The pseudowire class name must match the name specified when you
	Example:	created the pseudowire class, but you can use a different pw-class in the
		backup peer command than the name used in the primary xconnect
	Router(config-if-xcon)# backup peer	command.
	10.10.10.11 344 [pw-class pwclass1]
Step 10
	backup delay enable-delay	• enable delay—Specifies how long (in seconds) the backup
	{disable-delay never}	pseudowire VC should wait to take over, after the primary pseudowire
		VC goes down. The range is 0 to 180.
	Example:	• disable delay—Specifies how long the primary pseudowire should
	Router(config-if-xcon)# backup	wait, after it becomes active to take over for the backup pseudowire
	delay 30 60	VC. The range is 0 to 180 seconds. If you specify the never keyword,
		the primary pseudowire VC never takes over for the backup.
