Description (partial)

Symptom: The DHCPv6 server does not reply to REBIND messages 
coming from the DHCPv6 clients if  they come along a 
virtual interface which is different from the one used to exchange the 
previous DHCPv6 messages
Conditions:The symptom is observed on a router hosting the DHCPv6 
server in a Virtual Template. So when a DHCPv6 client connects, disconnects
 and reconnects, it is likely that the new virtual interface index
 is different from the initial one.
