The operator probably has two separate DHCPv6 servers running for redundancy. As such, and in the absence of DHCPv6 failover support, both servers will send an ADVERTISE. Does one server have a higher preference value than the other?<div>

</div>Please pardon my ignorance, but what's that second AdvertiseXID in<br>
there? It has a different server identifier and assigns a different<br>
address. The Confirms all seem to be for the address in the first<br>
AdvertiseXID, not the 2nd.<br>
<br>
Is this normal?<br>
