Ok, when I tried it earlier, it didn't work without "p-arp". Let me see
whether I can explain this. S1 is the subnet that host belongs and s2 is the
subnet to which it has been moved to.
When you move the host (windows 95, for example) to the S2, it will still
have the S1 subnet default-gateway and it will to arp that gateway. Unless,
you configure the p-arp on the mobile router, it will not respond for the
arp broadcast.
When I tried this, just to experiment, I changed the default gateway on the
host pointing to the S2 address, and I disabled the p-arp on S2 router.
Then, the host will arp for S2. Make sense????
You can avoid all these by using IRDP.
