Hello
The information for the IP LAN mobility is correct. I don't if you know
this, but the interface command for IP mobile arp needs the access-group
command also applied on the same line followed by the access-list # created.
example:
int f0/0
ip mobile arp access-group 44
exit
access-list 44 permit x.x.x.x (wild card mask)
router ospf 1
redistribute mobile subnets
