To ensure that router R2 removes the directly connected route for 192.168.1.0/24 from its routing table when the cable between router R1 and the Secure FTD device is disconnected, the network engineer must implement the "Propagate Link State" option on the Secure FTD device. This option allows the FTD to propagate the link state changes to adjacent devices, ensuring that the disconnection is recognized and the routing table is updated accordingly.

Steps:

Access the FTD device configuration via FMC.

Navigate to the interface settings for the relevant interfaces.

Enable the "Propagate Link State" option for the interfaces connected to R1 and R2.

Deploy the changes to the FTD device.

This configuration ensures that the link state changes are communicated to router R2, prompting it to remove the disconnected route from its routing table.
