.. cfgcmd:: set service dhcpv6-server shared-network-name <name> subnet

<prefix> prefix-delegation prefix <pd-prefix> prefix-length <lenght>
Hand out prefixes of size `<length>` to clients in subnet `<prefix>` when
they request for prefix delegation.
Delegate prefixes from `<pd-prefix>` to clients in subnet `<prefix>`. Range
is defined by `<lenght>` in bits, 32 to 64.
.. cfgcmd:: set service dhcpv6-server shared-network-name <name> subnet

Hand out prefixes of size `<length>` in bits from `<pd-prefix>` to clients
in subnet `<prefix>` when the request for prefix delegation.
.. cfgcmd:: set service dhcpv6-server shared-network-name <name> subnet
<prefix> prefix-delegation prefix <pd-prefix> excluded-prefix <exclude-prefix>
Exclude `<exclude-prefix>` from `<pd-prefix>`.
.. cfgcmd:: set service dhcpv6-server shared-network-name <name> subnet
<prefix> prefix-delegation prefix <pd-prefix> excluded-prefix-length <length>
Define lenght of exclude prefix in `<pd-prefix>`.
**Example:**
* A shared network named ``PD-NET`` serves subnet ``2001:db8::/64``.
* It is connected to ``eth1``.
* Address pool shall be ``2001:db8::100`` through ``2001:db8::199``.
* It hands out prefixes ``2001:db8:0:10::/64`` through ``2001:db8:0:1f::/64``.
