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-name]
HomeAgent = <yes/no>
ForeignAgent = <yes/no>
.
.
|
Typically, your system has a single interface (le0, hme0, and so on) and supports both home agent and foreign agent
operations. If this is the situation 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 mipagent 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.

|
ReverseTunnel
|
yes or no FA or HA or both
|
Determines if mipagent provides reverse-tunnel
functionality.
The value yes means that both

The value FA means that the foreign agent
supports reverse tunneling. The value HA means that the
home agent supports reverse tunneling. The value both means
that both the foreign agent and home agent support reverse tunneling.

The value FA means
that the foreign agent requires a reverse tunnel. The value HA
means that the home agent requires a reverse tunnel.
