• Apply a prefix pool to an address pool—The DHCPv6 server dynamically assigns an IPv6 prefix
from the address pool to a DHCPv6 client.
Configuration guidelines
• To configure multiple static IPv6 prefix bindings, use the static-bind prefix command repeatedly.
• An IPv6 prefix can be bound to only one DHCPv6 client. You cannot use the static-bind prefix
command to modify the DUID, IAID, preferred lifetime, and valid lifetime of an existing static IPv6
prefix binding. To do so, you must remove the static IPv6 prefix binding first.
• Only one prefix pool can be applied to an address pool.
• An non-existing prefix pool can be applied to an address pool, but no prefix can be assigned from
the prefix pool until the prefix pool is created.
• You cannot use the prefix-pool command to modify an applied prefix pool, and its preferred
lifetime and valid lifetime. To do so, you must remove the application of the prefix pool first.
Configuration procedure
To configure IPv6 prefix assignment:
Ste
p
Command
Remarks
1. Enter system view.
system-view N/A
2. Create a prefix
pool.
ipv6 dhcp prefix-pool
prefix-pool-number prefix
{ prefix/prefix-len | prefix-number }
assign-len assign-len
This step is required for dynamic prefix
assignment.
By default, no prefix pool is configured.
A non-existing IPv6 prefix can be
specified, but the prefix pool takes effect
only after the IPv6 prefix is created.
For information about IPv6 prefix
configuration, see "Configuring basic IPv6
settings."
3. Create a DHCPv6
address pool and
enter its view.
ipv6 dhcp pool pool-number
[ vpn-instance vpn-instance-name ]
By default, no DHCPv6 address pool is
configured.
4. Specify an IPv6
subnet for dynamic
address
assignment.
network
{ network-address/prefix-length |
prefix prefix-number
[ sub-prefix/sub-prefix-length ] }
[ preferred-lifetime preferred-lifetime
valid-lifetime valid-lifetime ]
This step is optional if you want to apply an
address pool to the DHCPv6 server when
enabling the DHCPv6 server on the
interface.
By default, no IPv6 subnet is configured for
dynamic address assignment.
