Each IPv6 address or IPv6 prefix has a default life time assigned by the server. At certain intervals, a client asks the server to renew its address (called renew/rebind times).
However, if the WAN prefix changes, for example, due to disconnection and reconnection of an Internet connection or a request for a new prefix, the server has no way to inform the network devices that the prefix or address has changed. This means that a client is still using an old address or an old prefix, and can no longer communicate with the Internet.
The reconfigure feature allows the DHCPv6 server to require the clients in the network to request a renewal of leases / bindings.
- SNMP ID:

- Possible values:
- Off
- Disables the reconfigure function
- Reject
- Clients that have used the Reconfigure Option in queries are rejected by the server and are not assigned an address, prefix or other options.
- Allow
- If the client sets the Reconfigure Option in queries, the server negotiates the necessary parameters with the client in order to start a reconfiguration at a later time.
- Require
- Clients have to set the Reconfigure Option in queries, otherwise the client rejects these clients. This mode is makes sense when you want to ensure that the server only serves clients which support Reconfigure. This ensure that all clients can use Reconfigure to update their addresses, prefixes, or other information at a later point in time.
- Default:
- Off
