HP MSR2000/3000/4000 Router Series Layer 3 - IP Services Command Reference

285
If a DHCPv6 option is specified by both the dedicated command and the option command, the DHCPv6
server preferentially assigns the content specified by the dedicated command. For example, if a DNS
server address is specified by the dns-server command and the option 23 command, the server uses the
address specified by dns-server command.
Examples
# Configure Option 23 that specifies a DNS server address 2001:f3e0::1 in DHCPv6 address pool 1.
<Sysname> system-view
[Sysname] ipv6 dhcp pool 1
[Sysname-dhcp6-pool-1] option 23 hex 2001f3e0000000000000000000000001

Only one prefix pool can be applied to an address pool.
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.
