Home Agents and Basic Operation
In Mobile IPv6 basic operation, a Correspondent Node sends data-packets to the Mobile Node using the
Mobile Node’s home address. A Home Agent (HA), a node or router on the Mobile Node’s home network,
intercepts these data-packets and tunnels them to the Mobile Node’s current Care-of Address, as show in
Figure 1-1, Correspondent Node to Mobile Node in Basic Operation.

The Mobile Node sends data-packets to the Correspondent Node through its Home Agent, as shown in
Figure 1-2, Mobile Node to Correspondent Node in Basic Operation.
