Creating an IP Aliases File
You can save IP alias settings in the /etc/config/ipaliases.options file so they are automatically assigned during the network initialization process. The ipaliases.options file is read by the network script if the /etc/config/ipaliases file contains the value on. Use the procedure below to create an ipaliases.options file and assign IP aliases automatically during network initialization:
Edit ipaliases.options using your favorite editor:
# vi /etc/config/ipaliases.options
Your entries should look similar to the example below. In this example, broadcasting is performed on the Ethernet but not the FDDI network:
ec0 128.64.56.51 netmask 0xffffff00 broadcast 128.64.56.255
ec0 128.64.56.12 netmask 0xffffff00 broadcast 128.64.56.255
ipg0 190.111.79.16 netmask 0xffffff00
ipg0 190.111.79.10 netmask 0xffffff00
