Thanks Scott!
I did find more detailed info about Mobile IP under the section of
the doc cd for the 3200 Mobile Router. It's under Access Servers &
Routers > All Access Products > Mobile Access Router > Configuration
for the Cisco 3200...
Unlike the 12.2 configuration guide, in the Introduction to Mobile IP
document here it actually tells you that the Agent discovery and
solicitation messages between MN and HA/FA use the IRDP protocol like
Scott mentioned.
