I work for a WISP and we currently have public networks sub-netted all over and we're running low on public IPs. I plan on switching the network to Mikrotik from Cisco, having larger /22 or so sized subnets and giving sites access to them by using MPLS/VPLS. It sound like this is becoming more popular.

I'm trying to see which hardware I should get for this project. So far I plan on using CRS328-24P-4S+RM on sites where I need POE and CRS326-24G-2S+RM on sites where I don't. I plan on having all of the public gateways back on 1 router back at our DIA and terminating the VPLS tunnels there. What router should I use there? We have 1 /20, 1 /23, and 1,22 that I plan on breaking up into 5 /22's and 1 /23. We currently have about 2.4Gbps of traffic that it would need to route, but I would like to plan for 5-10Gbps. I was looking at the CCR1036-8G-2S+.

I have a separate DHCP server that I was going to have the new router relay to but I might also have that router just do DHCP if that ends up making more sense.

Also, if anyone has done something like this recently and has any advice, that would be great. I'll probably create a couple different threads for design questions later.

Thank you.

We work on a lot of WISPs with MikroTik using the design you mentioned with MPLS/VPLS.

I would not use the CRS hardware for anything other than Layer 2 in this type of network. The CPU is not designed for heavy Layer 3 workloads. I'd look at using the CCR family along with a stackable Layer 2 or 3 switch for the core.

The CCRs are the most common type of router deployed for this type of design.

Well shucks. That adds about 23 grand to the project. I guess I'll need to rethink the whole thing.

Would I be able to pay you to go over this design in a little more detail with me?

No problem, shoot an e-mail to consulting@iparchitechs.com with your contact info.

We've designed and built hundreds of startup WISPs over the last 10 years and can help you work on the hardware, design and configuration to deploy a carrier-grade solution with MIkroTik for a specific budget.
