users by using a specific DHCP server. This prevents address pool resource wastes and
unnecessary address reallocation.

Run:
system-view
The system view is displayed.
Run:
ip pool pool-name [bas { local | remote | rui-slave } | server ]
ip pool pool-name bas { local | remote } rui-slave
ipv6 pool pool-name [bas { local | remote } rui-slave ] ]
An address pool is created and the address pool view is displayed.
A local primary address pool and a rui-slave (local rui-slave) secondary address pool are
configured on the master or slave device.
NOTE
A remote DHCP server can be used to allocate addresses for users logging in to the master and slave
devices. If a remote DHCP server is used, a remote address pool must be configured on the master
device; a remote rui-slave address pool must be configured on the slave device; the address pools
must be associated with the DHCP server group on the remote DHCP server.
Run:
gateway ip-address mask
The gateway address of the address pool is set.
The gateway address and mask of the address pool are used to check whether an address
segment is in the same subnet as the gateway address. The gateway address and mask of
the address pool must be set before the address segment is set.
Run:
section section-num start-ip-address [ end-ip-address ]
The address range is configured for an address pool.
The primary and secondary address pools must use different address ranges on the master
and slave devices. The master device's primary address pool and the slave device's
secondary address pool share an address range. The master device's secondary address pool
and the slave device's primary address pool share an address range. This prevents
unnecessary address re-allocation after a master/slave device switchover occurs.
NOTE
If a rui-slave address pool (configured using the local rui-slave parameter) is used,
l The remote DHCP server and its parameters must be configured.
l If a rui-slave address pool (configured using the local rui-slave parameter) is bound to an RBS,
the address pool automatically used the peer IP address in the RBS as a DHCP server IP address,
without additional configuration.
Before performing the following step, ensure that the dhcp-server group group-name remote-
backup-service rbs-name command is run in the system view to specify the name of a DHCP server
group and associate the DHCP server group with a specified RBS.
