7.2 Disconnected Parent

The same configuration, as shown in Section 7.1, can be used to give an overview of the disconnected parent case (see Figure 7-4).

Disconnected Parent Example: Initial Setup Figure 7-4 Disconnected Parent Example: Initial Setup

In this scenario, Router Node 1 is disconnected, severing communication between the Border Router and Router Nodes 2 and 3, as shown in Figure 7-5.

Disconnected Parent Example: Disconnect RN1 Figure 7-5 Disconnected Parent Example: Disconnect RN1

When the disconnection of the parent router node is detected by Router Node 2, Router Node 2 tries to connect to the closest available alternative (see Figure 7-6). This is Router Node 4 in this scenario
