Parameters
prefix-pool-number
: Specifies a prefix pool number in the range of 1 to 128.
prefix { prefix-number | prefix/prefix-len } : Specifies a prefix by its ID or in the
format of prefix / prefix length . The value range for the prefix-number argument is 1 to
1024. The value range for the
prefix-len
argument is 1 to 128.
assign-len assign-len
: Specifies the assigned prefix length. The value range is 1 to 128, and
the value must be greater than or equal to
prefix-len.
The difference between
assign-len
and
prefix-len
must be no more than 16.
vpn-instance vpn-instance-name
: Specifies an MPLS L3VPN instance by its name, a
case-sensitive string of 1 to 31 characters. To create a prefix pool for the public network, do not
specify this option.
Usage guidelines
Different prefix pools cannot overlap.
To modify a prefix pool, execute the
undo ipv6 dhcp prefix-pool
command to delete the
prefix pool, and then execute the
ipv6 dhcp prefix-pool
command.
Deleting a prefix pool clears all prefix bindings from the prefix pool.
When you specify a prefix by its ID, follow these restrictions and guidelines:
•
This command does not take effect if the prefix does not exist. This command takes effect after
the prefix is created.
•
Do not specify the same prefix for different prefix pools in a VPN.
•
If the prefix that the ID represents is changed, the prefix range in the prefix pool accordingly
changes.
Examples
# Create IPv6 prefix 88:99::/32 with ID 3. Configure prefix pool 2 with IPv6 prefix 3 and an assigned
prefix length of 42. Prefix pool 2 contains 1024 prefixes from 88:99::/42 to 88:99:FFC0::/42.
<Sysname> system-view
[Sysname] ipv6 prefix 3 88:99::/32
[Sysname] ipv6 dhcp prefix-pool 2 prefix 3 assign-len 42
# Create prefix pool 1, and specify prefix 2001:0410::/32 with an assigned prefix length of 42. Prefix
pool 1 contains 1024 prefixes from 2001:0410::/42 to 2001:0410:FFC0::/42.
<Sysname> system-view
[Sysname] ipv6 dhcp prefix-pool 1 prefix 2001:0410::/32 assign-len 42

ipv6 dhcp server

the interface uses a global address pool to assign configuration information to a client.
Use

to restore the default.
