Router mobility HA

I'm not sure if this is a correct forum for this topic but I hope if anyone can help me with this.

I'm  trying to setup router mobility topology without a foreign agent  (FA). I believed we can do this by using colocated care-of-address  (ccoa-only) method.

Topology:

HA <-->   GW   <-->     MN

         172.19.200.0/24

Here is partial of my configuration

HA config:

========

interface FastEthernet1/0

ip address 172.19.200.1 255.255.255.0

:

ip mobile home-agent

ip mobile virtual-network 1.2.3.0 255.255.255.0

ip mobile host 1.2.3.4 virtual-network 1.2.3.0 255.255.255.0

ip mobile mobile-networks 1.2.3.4

ip mobile secure host 1.2.3.4 spi 100 key ascii cisco algorithm md5 mode prefix-suffix

MN config

=======

interface FastEthernet0/1

ip address 172.19.200.3 255.255.255.0

ip mobile router-service roam

ip mobile router-service collocated gateway 172.19.200.254 ccoa-only

duplex auto

speed auto

no routing dynamic

!

ip mobile secure home-agent 172.19.200.1 spi 100 key ascii cisco algorithm md5 mode prefix-suffix

ip mobile router

address 1.2.3.4 255.255.255.0

collocated single-tunnel

home-agent 172.19.200.1

register extend expire 10 retry 3 interval 5

(assumed all interfaces are properly connected and ip addresses are pingable from both end)

MN LOG:

When Mobile Node (MN) try to register with Home Agent (HA) it always failed with following msg :

"MR 1.2.3.4 is not configured for dynamic mobnet registration"

What am I missing here ? Please advice.

Thanks in advance,
