This read-create object holds the destination address of an IP Reachable Address entry, which may represent a network, subnetwork, or host address that this router advertises reachability for over this circuit; it follows the manualOrAutomatic behaviour, meaning it can be either statically configured or automatically derived. It is what actually appears as a reachable IP prefix in this router's Level 1 or Level 2 LSPs. For example, an administrator manually adding a stub network's prefix would set csIsisIPRADest to that network's address so IS-IS advertises it network-wide.
