Configuration guidelines • An IPv6 prefix can be bound to only one DHCPv6 client. You cannot modify bindings that have been created. To change the binding for a DHCPv6 client, you must delete the existing binding first. • Only one prefix pool can be applied to an address pool. You cannot modify prefix pools that have been applied. To change the prefix pool for an address pool, you must remove the prefix pool application first. • 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. Configuration procedure To configure IPv6 prefix assignment: Step 1. Enter system view. Command system-view Remarks N/A 2. (Optional.) Specify the IPv6 prefixes excluded from dynamic assignment. ipv6 dhcp server forbidden-prefix start-prefix/prefix-len [ end-prefix/prefix-len ] By default, no IPv6 prefixes in the prefix pool are excluded from dynamic assignment. If the excluded IPv6 prefix is in a static binding, the prefix still can be assigned to the client. To exclude multiple IPv6 prefix ranges, repeat this step. 3. Create a prefix pool. 4. Create a DHCPv6 address pool and enter its view. ipv6 dhcp prefix-pool prefix-pool-number prefix prefix/prefix-len assign-len assign-len This step is required for dynamic prefix assignment. By default, no prefix pool is configured. ipv6 dhcp pool pool-name By default, no DHCPv6 address pool is configured. 5. Specify an IPv6 subnet network prefix/prefix-length for dynamic assignment. [ preferred-lifetime preferred-lifetime valid-lifetime valid-lifetime ] 6. Configure static or dynamic prefix assignment. • Configure a static prefix binding: static-bind prefix prefix/prefix-len duid duid [ iaid iaid ] [ preferred-lifetime preferred-lifetime valid-lifetime valid-lifetime ] • Apply the prefix pool to the address pool: prefix-pool prefix-pool-number [ preferred-lifetime preferred-lifetime valid-lifetime valid-lifetime ] By default, no IPv6 subnet is specified for dynamic assignment. Use at least one command. By default, no static or dynamic prefix assignment is configured for an address pool. To add multiple static IPv6 prefix bindings, use the static-bind prefix command. 148
