You're right, of course. I tried it, but still no soap. This is getting
frustrating. Thanks again for pointing this out. I wish there were more
documentation on the feature.

  Hi Doug,

  I've not check the doc for the config, but I see that the mask in your acl
might be wrong, shouldn't it be 0.0.0.63?

Thanks for the info. I tried your config (I lost the access list), but
still no success. Your explanation makes sense to me - however, I don't
know specifically how to configure the workstation to request a gateway, or
even if it is necessary. I have tried to make this entry blank, but it
didn't help. Anyway, this would appear to be my problem. I will read up on
this some.

  As far as I understood LAM, the workstation with the static IP address
    will
  once connected to a different network do a arp request for its configured
gateway.
Because of the [IP MOBILE ARP] configured on the interface the router will
answer, with the gateway address, and put a mobile host route in its
    routing
  table.

Then, because redistribute mobile, the routing protocol will redistribute
this route as a connected network.

I tried this with just the commands,

router mobile
!
interface Ethernet 0
ip mobile arp
!
router ospf 1
redistribute mobile subnets
!

On the router the station connected to, so not on the originating network.

And it worked.

Jacques

AFAIK, the acl is required to tell router mobile what specifically to
    treat
  as mobile. Otherwise, it would just have the interface to go on, and of
course, ITS IP addr is another subnet.
As far as routing. I have included the redistribute mobile command in the
config, which is what I understand is required. Wish I had a sample to
    work
  with. It may be that IRDP is required, but I don't think so - at least
    it
  doesn't show in the limited documentation.

    Sorry, overlooked that one, and your correct.

Have you tried this without the acl?
Is the mobile route (a host route) in the ospf table?

"router mobile" is already there, right above the router ospf 1
      command.
  I
    also put in a distance, although I don't think that this is required.
AFAIK, there is no "ip router mobile" command. Is that correct?

      On router 5 you have to add the command

ip router mobile

Subject: Problem getting local mobility to work

I have been trying to get mobile IP to work in a local network. For
purposes
of this discussion, the topology is like so:

VLAN11 (170.10.11.0/26) -- Rtr2 -----Frame Relay --Rtr5 -- VLAN34
(170.10.10.1/26)

Rtr2's VLAN I/F is EIGRP, which redistributes into OSPF (and OSPF into
EIGRP),
while the FR ntwk is Area 0 OSPF. VLAN 34 is in area 2.

Full routing in the network is available, no bugs or issues.

I configured a PC with an IP addr of 170.10.11.5/26 (gateway
        170.10.11.1,
    which is the Rtr2 I/F), and move it to VLAN 34, but it does not start
        up
  Router Mobile, nor can I ping anywhere out of the PC. I have
        installed
  the
      commands as I understand from Cisco documentation, but no soap. Does
        any
    one
have a working config or a link showing this with an example?

Following is my current config of Rtr5, if needed. TIA!
