Hello Dears ,
kindly be noted that I don’t understand why we write network although we write subnet mask when we assigning IP to interface . Kindly check the attached screenshot.
What is your question actually. Ask a clear question if you want.
That last . is probably causing the error (reason for the red color)
10.10.10.10/24 and not like you try 10.10.10.10**.**/24
Because… is normal.
