Help Please! ISP Modem > Switch - Location 1 > Switch Location 2 > Main Router for Site?

Hi All,

I'd be very grateful for some help and advice from the wise Networking folks on here please.

I've been trying to research this but didn't find anything that I could use to get a grip on this issue.

I do understand that the below isn't an ideal starting point - But we've been pushed into this and need to work out a solution now.

Basically due to the size of our large Building our ISP would only run our fibre connection to a small switch cabinet that's about 150 meters from our main comms room. (Location is near front of building and point of entry for fibre cable etc etc.)

The switches in this cabinet ( Cisco Catalyst 2960-L series) are connected back to our core switch in our main comms room by fibre cables so performance should be acceptable.

I'm trying to determine the accepted solution or best approach to getting everything to work.

Basically I need to try and get the below working:

ISP Modem > Switch - Location 1 >>> Fibre Link >>> Switch - Location 2 > Main Router for Site.

This main router is a Sonicwall TZ300 that we also use for our incoming VPN connections to the Site.
