problems:

• “Mobile Node Registration and De-registration Problems” on page 98
• “Routing Problems - Deleted Mobile IPv4 Routes” on page 107
Daemon Will Not Run
The mipd or miprod daemon will not start (the mipadmin -start command returns an
error) or the mipadmin -status command returns the following error:
mipadmin: No Mobile IP daemon was found running; the ’status’ query does
not apply
Solution
Verify the items in the subsections listed below.
syslog
Check the syslog file (the default file is /var/adm/syslog/syslog.log) for errors when
starting the daemon. Use the mipadmin -logevents command.
Failed to bind ipc_socket The following log message indicates that the daemon did
not start because it could not create the /var/adm/mip/admin_ipc_socket domain
socket it uses to communicate with mipadmin:

- No such file or directory
Verify that the /var/adm/mip directory exists. Create this directory if it does not exist.
You can re-install the product to create this directory.

a Diameter AAA Disconnect Peer Request (DPR), possibly because the AAA server
shutdown.
