additionally it needs to pass through transit from other nodes on the ring (example – traffic from
7210-2 to 7210-3 OR from 7210-2 to 7750 –SR onto the core network).
Without Default QinQ SAPs, user would need to configure a service on 7210-1, with access-
uplink SAPs for each service originating on some other node in the ring. With support for Default
QinQ SAPs, all traffic which does not need to be delivered to any customer service configured on
7210-1 can be switched using the EPIPE service. The example shown below provides the sample
configuration commands in this scenario:
ALA-1>config>service# epipe 8 customer 1 svc-sap-type null-star create
