Dhcpv6 Pd Sub Client - Siemens SCALANCE XM-400 Configuration Manual

● Prefix Name
Enter the prefix name that will be further distributed by the DHCPv6 router. Can only be
edited with the "Prefix Delegation" procedure. The DHCPv6 router stores IPv6 prefix of the
DHCPv6 server under this name.
● Rapid Commit
When enabled the procedure for the IPv6 address assignment is shortened. Instead of 4
DHCPv6 messages (SOLICIT, ADVERTISE , REQUEST, REPLY) only 2 DHCPv6
messages (SOLICIT, REPLY) are used. You will find further information on the messages
in RFC 3315.
Steps in configuration
1. Select the interface
2. Enable the DHCPv6 client.
3. Select the mode.
4. Enter a name for the prefix. Only necessary if "Prefix Delegation" is set as the mode.
5. Click the "Set Values" button.
5.7.3.2

DHCPv6 PD Sub Client

On this page you specify which IPv6 interfaces of the DHCPv6 client will adopt the prefix. This
achieved by assigning the prefix name followed by a prefix and the required prefix length to
them as the IP address. Here, the first bits of the configured prefix are replaced by the values
stored in the prefix name.
Example:
Under the prefix name "test", the following IPv6 prefix is stored: 2001:DB8:1234::/48
Prefix = 2002:AF9:5678::1
Prefix length = 64
This results in the following IPv6 address 2001:DB8:1234::1
