Greetings! Looking for advice on redoing our company's infrastructure. Currently we have a small dark fibre switched network running between C3560-Xs and a C2960-X at 1Gb, with a bunch of smaller satellite sites connected via various ways... 1Gb fiber, or VPN tunnels through the firewall. The way we're going is to change this setup into a much cleaner metro ethernet setup. But I don't have much first-hand experience in it, only in the lab. We're supposed to have EVCs from the smaller sites set up with two paths each, one to one data centre, and another to the other data centre. One data centre will have a fibre WAN link and a firewall. We're all Cisco, and that's where my current experience is. But if our provider is doing things like Q-in-Q, I'm not sure we have the capability right now to decapsulate that cleanly, as we're at IP and LAN base, not to mention our shit is pretty old. We're prepared to spend some $ but I want to make sure it's getting spend wisely. I need to figure out what should be placed at each smaller site, and something newer and beefier at the two data centres to act as head-ends.
First though, I need to consider whether what I need are even routers, or what would be best here are good layer 3 switches. We are planning on each site having about 5 VLANs or so. They would stay connected locally at the site and would only need to be routed through one SVI ideally. Is anybody else running this kind of setup?
