Advertisements Section
The Advertisements section contains the HomeAgent and ForeignAgent labels, as well as other labels.
You must include a different Advertisements section for
each interface on the local host that provides Mobile IP services. The Advertisements section has the following syntax:
[Advertisements interface]
HomeAgent = <yes/no>
ForeignAgent = <yes/no>
.
.
|
Typically, your
system has a single interface, such as eri0 or hme0,
and supports both home agent and foreign agent operations. If this situation
exists for the example hme0, then the yes value
is assigned to both the HomeAgent and ForeignAgent labels
as follows:
[Advertisements hme0]
HomeAgent = yes
ForeignAgent = yes
.
.
|
For advertisement over dynamic interfaces, use '*' for the device ID
part. For example, Interface-name ppp* actually
implies all PPP interfaces that are configured after the mipagent daemon
has been started. All the attributes in the advertisement section of a dynamic
interface type remain the same.
The following table describes
the labels and values that you can use in the Advertisements section.

The value FA means that the foreign agent requires
