Mobile IP testing

I am trying to test Mobile IP in a lab scenario.

X ----ethernet 2620 serial.........serial2620ethernet -----Y

The set up is like this. R1 and R2 are 2 2620s connected by serial link. R1 has ethernet falling in network X. R2 has ethernet falling in network Y. R1 is configured as Home agent, R2 as Foreign agent. R2 has IRDP enabled on ethernet interface.

When the laptop is moved from R1s ethernet to R2, I can see a mobile host route (/32) on the R2s routing table ( M). But the registration between the mobile host and the HA is not happening.

Does the laptop require a Mobile IP client, to contact or register with the HA ?

Anybody who have played with Mobile IP , Please advise
