2.21 prefix-delegation

o Command: prefix-delegation <ipv6-prefix/prefix-length> <client-DUID> [iaid

<iaid>] [lifetime {<valid-time> | infinity} {<preferred-time> | infinity}]

o no prefix-delegation <ipv6-prefix/prefix-length> <client-DUID> [iaid <iaid>]

 Function: To configure dedicated prefix delegation for the specified user. The no form

of this command will remove the dedicated prefix delegation.

 Parameters: <ipv6-prefix/prefix-length> is the length of the prefix to be allocated to

the client. <client-DUID> is the DUID of the client. DUID with the type of DUID-LLT and

DUID-LL are supported, the DUID of DUID-LLT type should be of 14 characters. <iaid> is

the value to be appended in the IA_PD field of the clients’ requests. <valid-time> and

<preferred-time> are the valid life time and the preferred life time of the IPv6 address

allocated to the clients respectively, in seconds, and its value is allowed between 1 and

31536000. However, <preferred-time> should never be bigger than <valid-time>. If not

configured, the default <valid-time> will be 2592000, while <preferred-time> will be

604800. The infinity parameter means the life time is infinity.

 Command Mode: DHCPv6 Address Pool Configuration Mode.

 Default: Disabled.

 Usage Guide: This command configures the specified IPv6 address prefix to bind with

the specified client. If no IAID is configured, any IA of any clients will be able get this

address prefix. At most eight static binding address prefix can be configured for each

address pool. For prefix delegation, static binding is of higher priority than the prefix

address pool.

 Example: The following command will allocate 2001:da8::/48 to the client with DUID as

0001000600000005000BBFAA2408, and IAID as 12.

 Switch(dhcp-1-config)#prefix-delegation 2001:da8::/48

0001000600000005000BBFAA2408 iaid 12

2.22 prefix-delegation pool

 Command: prefix-delegation pool <poolname> [lifetime {<valid-time> | infinity}

{<preferred-time> | infinity}]

 no prefix-delegation pool <poolname>

 Function: To configure prefix delegation name used by DHCPv6 address pool. The no

form of this command deletes the configuration.

 Parameters: <poolname> is the name of the address prefix pool, the length name

string should be less than 32. <valid-time> and <preferred-time> are the valid life time

and the preferred life time of the IPv6 address allocated to the clients respectively, in

seconds, and its value is allowed between 1 and 31536000.However, <preferred-time>

should never be bigger than <valid-time>. If not configured, the default <valid-time>

will be 2592000, while <preferred-time> will be 604800. The infinity parameter means

the life time is infinity.

 Command Mode: DHCPv6 address pool configuration mode.
