Using the MAR3200 in Mobile Environments
•
The MR then sends in Registration Request (RRQ) to the HA.
•
The HA authenticates MR by sending a Registration reply (RRP) to the MR.
•
The HA provides a gratuitous APR update for the home network, then creates a GRE tunnel to the
FA if using Foreign Agent CoA (FACoA), or to the MR if you are using CCoA. It then adds a host
route to the MR.

Now, the MR has reached a registered state with the HA and the HA has set up a binding table entry
for the MR CoA. It will then tunnel and route traffic destined for the MR.
for the MR CoA. It will then tunnel and route traffic destined for the MR.
•
At this point, the MR is registered through a Mesh WLAN to its HA using the FACoA.
If any devices attached to the Cisco 3200 Series router must communicate with nodes on the home
network, they send the data to the Cisco 3200 Series router and Mobile IP tunnels the data to the
HA, with any traffic directed to MR clients tunneled from the HA to the MR. A simple Mobile IP
network with FACoA for Mesh and Collocated Care of Address (CCoA) for cellular is illustrated in

If the MAR3200 is not in the vicinity of a wireless LAN hotspot it can use a backup wireless service
such as cellular modem to deliver the data.

In this case, the Cisco 3200 generates a CCoA from the IP address it acquired from the service
provider network and registers its CCoA with the HA. This CCoA address is the MR’s own interface
IP address it acquired via DHCP from the service provider. The registration process is similar to the
process for CoA registration.
