Syntax ipv6 dhcp server forbidden-prefix start-prefix/prefix-len [ end-prefix/prefix-len ] undo ipv6 dhcp server forbidden-prefix start-prefix/prefix-len [ end-prefix/prefix-len ] Default No IPv6 prefixes in the DHCPv6 prefix pool are excluded from dynamic allocation. Views System view Predefined user roles network-admin Parameters start-prefix/prefix-len: Specifies the start IPv6 prefix. The prefix-len argument specifies the prefix length, ranging from 1 to 128. end-prefix/prefix-len: Specifies the end IPv6 prefix. The prefix-len argument specifies the prefix length, ranging from 1 to 128. The value for end-prefix cannot be lower than that for start-prefix. If this argument is not specified, only the start-prefix/prefix-len is excluded from dynamic allocation. If it is specified, the prefixes from start-prefix/prefix-len to end-prefix/prefix-len are all excluded. Usage guidelines You can exclude multiple IPv6 prefix ranges from dynamic allocation. If the excluded IPv6 prefix is in a static binding, the prefix can still be assigned to the client. The prefix or prefix range specified in the undo form of the command must be the same as the prefix or prefix range specified in the command. To remove a prefix that has been specified as part of a prefix range, you must remove the entire prefix range.

Parameters
start-prefix/prefix-len
: Specifies the start IPv6 prefix. The
prefix-len
argument specifies the prefix length,
ranging from 1 to 128.
end-prefix/prefix-len
: Specifies the end IPv6 prefix. The
prefix-len
argument specifies the prefix length,
ranging from 1 to 128. The value for
end-prefix
cannot be lower than that for
start-prefix
. If this argument
is not specified, only the
start-prefix/prefix-len
is excluded from dynamic allocation. If it is specified, the
prefixes from
start-prefix/prefix-len
to
end-prefix/prefix-len
are all excluded.
Usage guidelines
You can exclude multiple IPv6 prefix ranges from dynamic allocation.
If the excluded IPv6 prefix is in a static binding, the prefix can still be assigned to the client.
The prefix or prefix range specified in the
undo
form of the command must be the same as the prefix or
prefix range specified in the command. To remove a prefix that has been specified as part of a prefix
range, you must remove the entire prefix range.
