...and what's the scenario? Ideally - both. In practice, you'll be facing constraints of different kinds.

DWDM-level protection is usually 'cheap' when you have enough fiber in the ground. It's on/off thing.

IP, IGP or MPLS layer protection is more universal, but usually harder to implement on a wider scale with tuning, testing and so on.
