Step 4: (Optional) Configure Care of Addresses (configure coa)
You do not need to configure Care-of Addresses for systems with only one interface. The
mipconfig utility will configure the IP address of a Foreign Agent interface as the
Care-of Address if you do not explicitly configure a Care-of Address. If the system is
multi-homed (it has more than one IP address), you may want to explicitly configure the
IP address of the fastest interface as the Care-of Address for all Foreign Agent
interfaces. To do this, use the mipconfig configure coa command:
c[onfigure] c[oa] [interface_name][fa_care-of_address[fa_care-of_address]
...]
Where:
interface_name is the name of an interface with Foreign Agent services.
fa_care_of_address is the IP address that will be included in FA advertisements as a
Care-of Address. You can specify a maximum of eight fa_care-of_address entries for
an interface.
You can also omit all options and mipconfig will prompt you for each option value. For
more information on the configure coa command, refer to “configure coa” on page 123.
