[c-nsp] Cisco Local Area Mobility - (LAM)

[Bogdan Radulescu]

Hello all,

I'm trying to use LAM on the following topology without much luck...

V100left---|3560G|---p-t-pL3link--|6500|---l2link--|7600|--V100right

V100left = SVI = 172.16.224.0/19
V100right = SVI = 192.168.224.0/19
V100right just random subnet, no clients
7600#interface Vlan100
         ip address 192.168.224.1 255.255.0.0
         ip mobile arp timers 1 1
        end

Between 6500 and 7600 i have a dynamic routing protocol and 6500 
announces V100left into BGP.
6500 has a static route for V100left to 3560G.
Connected to 7600 there is a server on V150 that needs to "talk" with 
these "clients"
Clients don't need to talk to each other.

I would like to move clients from V100 left to V100 right. I don't want 
to change ip addresses.
V100left will be moved when all clients move to the right.

It looks like 7600 detects the foreign ip on it's interface V100right, 
but doesn't put a "mobile" route for it.
All i can see is this:

debug ip packet detail gives me this

On the same 7600 i have several other VLANs with subnets from  
172.16.0.0/16 and some
L3 interfaces part of other VRFs


Is what i want possible or i\m wasting my time and yours? :)

Thank you
