Mobile Node is not Attempting to Register or De-register
If the Foreign Agent’s Agent Advertisements are not acceptable or available to the
Mobile Node, the Mobile Node will not register with the Foreign Agent. Similarly, if the
Home Agent’s Agent Advertisements are not acceptable to the Mobile Node, the Mobile
Node will not de-register when it returns to its home network. There will be no
indication on the Foreign Agent or Home Agent that this is occurring, except that the
Number of Registration Requests in the output for the mipadmin -status command will
not increment as expected.
Solution Verify that the parameters in the Agent Advertisements are acceptable to the
Mobile Node. Use the following command to view the contents of the Agent
Advertisements:
mipadmin -advertisements
Check that the Foreign or Home Agent is sending the Agent Advertisements to an
address that the Mobile Node understands and receives. Use the following command to
determine the address to which the Foreign or Home Agent is sending Agent
Advertisements:
mipadmin -configuration -interface
