Statically configured non-point-to-point IP address ipIfAddr, ipIfNetMask, and ipIfBcast must be provided. ipIfAddr and ipIfBcastAddr must be in the same subnet determined by ipIfNetMask 3. Statically configured point-to-point IP address ipIfAddr, ipIfDestAddr, ipIfNetMask, ipIfPointToPoint, and ipIfBcastEnabled must be provided. ipIfNetMask must be 255.255.255.255, ipIfPointToPoint must be true and ipIfBcastEnabled must be false.
