How to Configure Traffic Engineering - Fast Reroute Link Protection

	Command	Purpose
Step 7	rewrite ingress tag pop 1 symmetric	Specifies the encapsulation adjustment to be performed on a frame
		ingressing a service instance.
	Example:
	Router(config-if-srv)# rewrite ingress
	tag pop 1 symmetric
Step 8	xconnect peer-ip-address vc-id	Binds an attachment circuit to a pseudowire, and to configure an
	pw-classpw-class-name	Any Transport over MPLS (AToM) static pseudowire.
	Example:	• peer-ip-address—IP address of the remote provider edge (PE)
		peer. The remote router ID can be any IP address, as long as it
	Router(config-if-srv)# xconnect	is reachable.
	10.0.0.4 4 pw-class T41	• vc-id—The 32-bit identifier of the virtual circuit (VC) between
		the PE routers.
		• pw-class—Specifies the pseudowire class for advanced
		configuration.
		• pw-class-name—Pseudowire class name.
