Issue Description
Q:
How to comprehend the flow-process of how to process IPv6 on xdsl and GPBC?
Version of DSLAM:
V800R006C02 and V800R007Cx0
Type of Board:
VDMF, SHDSL, GPBC
Alarm Information
Null
Handling Process
A:
The discrepancies between diverse service-board refer to:
1.On VDMF: By default, VDMF board would grab IPv6 packets up to CPU depends on the packets whose attribution of VLAN is common, in the other word, if the VLAN is common, they would be grabbed up to CPU and then VDMF would discard this type of packets because of unrecognizable  IPv6. 
2.ON SHDSL, By default, if the attribution of VLAN was common, SHDSL board would grab IPv6 packets up to CPU, and discard them. However if the attribution of VLAN was QinQ, SHDSL board would ignore what type of format the IP packets are in QinQ, just forward them transparently. 
3.ON GPBC, by default, GPBC would grab and forward IPv6 packets no matter what the attribution of VLAN is.
