The device IP addresses of gateway network elements and non-gateway network elements must be set in the same network segment
Which of the following statements about 802.1Q is wrong?
The characteristic of the open DWDM system is that there are no special requirements for the optical interface of the multiplexing terminal, and only these interfaces are required to comply with the optical interface standard
recommended by ITU-T. The DWDM system adopts wavelength conversion technology to convert the optical signal of the multiplexed terminal into a specific wavelength, and the optical signal of different terminal equipment is converted into
different wavelengths that comply with ITU-T recommendations, and then multiplexed.
