Fiber and Wireless Project Deployment

[usman anwar]

Hello Everyone
I need a suggestion
We have 50+ sites in different locations and we are going to deploy a separate network for the communication between the sites.
all the sites are having (fiber as primary and wireless as secondary) redundant connectivity.
the primary communication between the sites is voice.
how should we configure our network.
shall we keep it a layer 2 or we should go towards the IP with some routing protocol that converge all the sites?

Don't waste money on making wireless as a secondary path.  

Use fibre as a primary and secondary system but use two different fibre path.  

Think the big picture, don't use Layer 2 and go straight to Layer 3.

thank you for the advise. actually wireless network is mandatory in our case. 

We will go with the layer 3.

The network will be full meshed. So, what Layer 3 features or protocols do you suggest us to deploy to achieve full redundancy.

actually wireless network is mandatory in our case.

Do all sites have direct line of sites of each other?

Wow.  That will be a very expensive solution if line of site to the adjoining site isn't established.
