HP MSR2000/3000/4000 Router Series Layer 3 - IP Services Command Reference

282
Parameters
start-ipv6-address: Specifies the start IPv6 address.
end-ipv6-address: Specifies the end IPv6 address, which cannot be lower than start-ipv6-address. If no
end IPv6 address is specified, only the start IPv6 address is excluded from dynamic allocation. If it is
specified, the IP addresses from start-ipv6-address through end-ipv6-address are all excluded from
dynamic allocation.
Usage guidelines
You can exclude multiple IP address ranges from dynamic allocation.
The IPv6 addresses of some devices such as the gateway and FTP server cannot be assigned to clients.
Use this command to exclude such addresses from dynamic allocation.
If the excluded IPv6 address is in a static binding, the address can still be assigned to the client.
The address or address range specified in the undo form of the command must be the same as the
address or address range specified in the command. To remove an IP address that has been specified as
part of an address range, you must remove the entire address range.
Examples
# Exclude IPv6 addresses of 2001:10:110::1 through 2001:10:110::20 from dynamic assignment.
<Sysname> system-view
[Sysname] ipv6 dhcp server forbidden-address 2001:10:110::1 2001:10:110::20

Parameters
start-prefix/prefix-len: Specifies the start IPv6 prefix. The prefix-len argument specifies the prefix length in
the range of 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
