Unrouting a complete PCB in Eagle means that all routed tracks on the board are reverted back into so-called ‘airwires’. Airwires are lines that show that there is a connection between 2 points on the board, but that no actual connection is routed yet.
Unrouting signals on a board is called ‘ripup’ in Eagle slang.
When I do the layout of a PCB, in a first step I always do an auto-route of the board to check that the design can physically be routed.
Since I prefer to route sensitive signals and power lines manually, I always need to ‘un-route’ the board after the autoroute check.
To unroute (or ripup) a complete board, first activate the ripup tool by clicking this icon:
Then, click the ‘go’ button in the top of the Eagle window to ripup all signals:

It is sometimes useful to know that turning off the view of the top layer will stop eagle from ripping up the top layer, this lets you keep some manual stuff on the top layer. Also see:
