HP VPN Firewall Appliances Network Management Command Reference

753
prefix: Specifies a prefix by specifying its ID or the prefix.
prefix-number: Specifies the ID of the IPv6 prefix, in the range of 1 to 1024.
prefix/prefix-len: Specifies the IPv6 prefix and prefix length. The value for the prefix-len argument is in the
range of 1 to 128.
assign-len assign-len: Specifies the length of the prefix assigned. The value range is 1 to 128. The
assign-len must be higher than or equal to the prefix-len, and the difference between them must be less
than or equal to 16.
Usage guidelines
The prefix ranges of the prefix pools cannot overlap. Otherwise, the prefix pools configured later does
not take effect.
You cannot modify an existing prefix pool.
Removing a prefix pool clears all bindings of prefixes assigned from the prefix pool.
You can specify a non-existing IPv6 prefix for the ipv6 dhcp prefix-pool command, but the command
takes effect only after you create the IPv6 prefix.
You cannot specify the same IPv6 prefix for different prefix pools.
When the IPv6 prefix used by the ipv6 dhcp prefix-pool command changes, the assignable prefix range
changes accordingly.
Examples
# Create prefix pool 1 that contains the prefix 2001:0410::/32 and specify the length of prefixes to be
assigned as 42. Prefix pool 1 can assign 1024 prefixes in the range of 2001:0410::/42 to
2001:0410:FFC0::/42.
<Sysname> system-view
[Sysname] ipv6 dhcp prefix-pool 1 prefix 2001:0410::/32 assign-len 42
# Create IPv6 prefix with the ID 3. Create prefix pool 2, and specify the prefix 3 and the length of the
prefixes to be assigned as 42. Prefix pool 2 can assign 1024 prefixes in the range of 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
ipv6 dhcp server
Use ipv6 dhcp server to enable the DHCPv6 server on the interface.
Use undo ipv6 dhcp server to remove the configuration.
