Page 224 highlights

A non-existing address pool can be applied to an interface, but the server cannot assign any prefix, address, or other configuration information from the address pool until the address pool is created.

Views System view Predefined user roles network-admin 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 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. 216

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

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.
