Co-located PDSN/FA and HA Configuration Example.
It should be noted that all interfaces defined within the 3GPP2 standards for 1x deployments exist in this configuration
as they are described in the two previous sections. This configuration can support communications to external, or
standalone, HAs and/or PDSNs/FAs using all prescribed standards.

Mobile IP Tunneling Methods
Tunneling by itself is a technology that enables one network to send its data via another network's connections.
Tunneling works by encapsulating a network protocol within a packet, carried by the second network. Tunneling is also
called encapsulation. Service providers typically use tunneling for two purposes; first, to transport otherwise un-routable
packets across the IP network and second, to provide data separation for Virtual Private Networking (VPN) services. In
Mobile IP, tunnels are used to transport data packets between the FA and HA.

The system supports the following tunneling protocols, as defined in the IS-835-A specification and the relevant
