After the configuration succeeds, the traffic of each PVC is forwards normally.
When you delete PVC100/101 from the PVC-Group of Router A, the phenomenon is as
follows:
z
On Router A, the packets that are originally sent to Router B through the PVC100/101
are transmitted by the PVC (PVC100/106) whose IP priority is set as the default value.
z
On Router B, the PVC100/101 status is still Up.
z
On Router B, all the packets that are sent to Router A through the PVC100/101 are still
sent from the PVC100/101.
All the packets that are sent to Router A from the PVC100/101 of Router B are lost.
