A read-create enumeration, defaulting to yes, determining whether opaque LSAs for the Wave key application are distributed into and received from this OSPF area, noting that Wave key opaque LSAs can only be enabled in one OSPF area device-wide. This controls distribution of wavelength/optical-key-related information via OSPF opaque LSAs into this area, and because it's restricted to a single area on the device, an admin must be careful only one area has this enabled at a time. An admin managing an optical transport network with OSPF-distributed wave key data would ensure this is set to yes on exactly one designated area and no on all others.
