The three methods are mutually exclusive and the use of a new method will result
in the IP address obtained by the old method being released. For example, if you
obtain an IP address by using the IP address configuration command, and then
use the ip address bootp-alloc command to apply for an IP address, the
originally configured IP address is deleted and a new IP address will be allocated
by BOOTP for the VLAN interface.
This chapter only introduces how to configure an IP address with the IP address
configuration command. For other two other two methods, refer to the part of
configuring and managing VLAN of this manual.

1.3 Configuring an IP Address for a VLAN Interface

Generally, it is enough to configure one IP address for a VLAN interface. However,
you can configure up to five IP addresses for a VLAN interface so that the interface
can be connected to several subnets. Among these IP addresses, one is the
primary IP address and the others are secondary ones.
