181Step Command Remarks1. Enter system view. system-view N/A2. (Optional.) Specify the IPv6addresses excluded fromdynamic assignment.ipv6 dhcp serverforbidden-addressstart-ipv6-address[ end-ipv6-address ][ vpn-instancevpn-instance-name ]By default, all IPv6 addressesexcept for the DHCPv6 server'sIP address in a DHCPv6 addresspool are assignable.If the excluded IPv6 address is ina static binding, the address stillcan be assigned to the client.To exclude multiple IPv6 prefixranges, repeat this step.3. Create a DHCPv6 addresspool and enter its view. ipv6 dhcp pool pool-name By default, no DHCPv6 addresspools exist.4. Specify an IPv6 subnet fordynamic assignment.network { prefix/prefix-length |prefix prefix-number[ sub-prefix/sub-prefix-length ] }[ preferred-lifetimepreferred-lifetime valid-lifetimevalid-lifetime ]By default, no IPv6 addresssubnet is specified.The IPv6 subnets cannot be thesame in different address pools.If you specify an IPv6 prefix byits ID, make sure the IPv6 prefixis in effect. Otherwise, theconfiguration does not takeeffect.5. (Optional.) Specify anon-temporary IPv6 addressrange.address range start-ipv6-addressend-ipv6-address[ preferred-lifetimepreferred-lifetime valid-lifetimevalid-lifetime ]By default, no non-temporaryIPv6 address range is specified,and all unicast addresses on thesubnet are assignable.6. (Optional.) Specify atemporary IPv6 addressrange.temporary address rangestart-ipv6-addressend-ipv6-address[ preferred-lifetimepreferred-lifetime valid-lifetimevalid-lifetime ]By default, no temporary IPv6address range is specified, andthe DHCPv6 server cannotassign temporary IPv6addresses.7. (Optional.) Create a staticbinding.static-bind addressipv6-address/addr-prefix-length |duid duid [ iaid iaid ][ preferred-lifetimepreferred-lifetime valid-lifetimevalid-lifetime ]By default, no static binding isconfigured.To add more static bindings,repeat this step.Configuring network parameters assignmentIn addition to IPv6 prefixes and IPv6 addresses, you can configure the following network parametersin an address pool:• A maximum of eight DNS server addresses.• One domain name.• One address family translation router (AFTR) domain name.• A maximum of eight SIP server addresses.• A maximum of eight SIP server domain names.You can configure network parameters on a DHCPv6 server by using one of the following methods:• Configure network parameters in a DHCPv6 address pool.
