Establishing Basic Operation

Correspondent Node to Mobile Node Data Path in Basic Operation

In basic mode, the Correspondent Node sends data-packets back to the Mobile Node through the Mobile

Node’s home address using the following procedure, and as shown in Figure 1-7, Data Path: Correspondent

Node to Mobile Node in Basic Operation:

1. The Correspondent Node addresses the data-packet to the Mobile Node’s home address.

2. The Mobile Node’s Home Agent captures the data-packet and encapsulates the data-packet in a new

data-packet with the Home Agent address as the source and the Mobile Node’s Care-of Address as the

destination. This process forms a tunnel between the Home Agent and the Care-of Address on the Mobile

Node.

3. The Mobile Node receives the encapsulated data-packet at its Care-of Address, decapsulates it, and

processes the original data-packet.
