generetator maze in runtime with peer to peer

I created a script that generates a runtime maze. What I want to do is simulate networking with peer to peer technology already set on unity. How can I make sure that the labyrinth generated by the server is the same who see clients?

 

Synchronize the seed that you used to generate the maze by making it a SyncVar, and then use that to generate the maze on each client.

 

in the settings I have not SyncVar. This component is connected to a vacuum GameObject that generates the maze
