The fast handover for MIPv6 states that when the Mobile node moves to the
new Access Router it MUST NOT use its new care-of address as a source
address unless it receives a F- BACK from its old Access Router. 

Consider then the scenario where the mobile node attaches
to the new access router but does not receive a F-BACK. The draft says that the mobile node
should resend the binding update. In this case then,  what address
does the mobile node use as the source address of the binding update it
re-sends to its old access router? Does it still use it old care-of
address? If it does, what about ingress filtering at the new access
router?
