Configuration Task List; Configuring Ipv6 Prefix Assignment; Configuration Guidelines - HP FlexNetwork MSR2003 Configuration Manual

6. Assignable IPv6 address/prefix in the address pool/prefix pool expected by the client.
7. Assignable IPv6 address/prefix in the address pool/prefix pool.
8. IPv6 address/prefix that was a conflict or passed its lease duration. If no IPv6 address/prefix is
assignable, the server does not respond.
If a client moves to another subnet, the DHCPv6 server selects an IPv6 address/prefix from the
address pool that matches the new subnet.
Conflicted IPv6 addresses can be assigned to other DHCPv6 clients only after the addresses are in
conflict for one hour.

Configuring IPv6 prefix assignment
Use the following methods to configure IPv6 prefix assignment:
•
Configure a static IPv6 prefix binding in an address pool—If you bind a DUID and an IAID
to an IPv6 prefix, the DUID and IAID in a request must match those in the binding before the
DHCPv6 server can assign the IPv6 prefix to the DHCPv6 client. If you only bind a DUID to an
IPv6 prefix, the DUID in the request must match the DUID in the binding before the DHCPv6
server can assign the IPv6 prefix to the DHCPv6 client.
•
Apply a prefix pool to an address pool—The DHCPv6 server dynamically assigns an IPv6
prefix from the prefix pool in the address pool to a DHCPv6 client.

Configuration guidelines

•
An IPv6 prefix can be bound to only one DHCPv6 client. You cannot modify bindings that have
been created. To change the binding for a DHCPv6 client, you must delete the existing binding
first.
•
Only one prefix pool can be applied to an address pool. You cannot modify prefix pools that
have been applied. To change the prefix pool for an address pool, you must remove the prefix
pool application first.
•
You can apply a prefix pool that has not been created to an address pool. The setting takes
effect after the prefix pool is created.
