	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:	• pop—Removes a tag from a packet.
	Router(config-if-srv)# rewrite ingress	• 1—Specifies the outermost tag for removal from a packet.

		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-srv)# bridge-domain 7
		• bridge-domain-id—Bridge domain identifier.
