Parameters and Values

<n>

0 Mobile IP disable, simple IP only.

1 Mobile IP preferred.

In the initial MIP registration, if the network does not support Mobile IP, the mobile automatically

reverts to Simple IP (forces a PPP renegotiation by sending an LCP C-Req). However, if a Mobile IP

session is registered and then the mobile enters a network that does not support Mobile IP, the

mobile will drop the session and inform the upper layers of the failure (for example, by dropping

DCD to a laptop).

2 Mobile IP Only. If the module is provisioned. Default: 2.

The mobile will make data calls only when the Mobile IP is supported in the network. During an

MIP session, if the mobile hands off to a network that does not support MIP, then the mobile will

drop the session and inform the upper layers of the failure (for example, by dropping DCD to a

laptop).
