Home Lab Network Redesign with Mikrotik Routers

I have two cable connections from Virgin Media coming into my house due to some annoying contract problems.

I originally had one line on the 60Mbit package, and the other on 100mbit, but when Virgin Media upgraded me to 120mbit I downgraded the 60mbit line to 30mbit to reduce costs.

Since I got into this strange arrangement with Virgin Media, I have been using a Cisco 1841 Integrated Services Router on the 30mbit line, and a Cisco 2821 Integrated Services Router on the 120mbit line, but I found that I wasn’t able to max out the faster line using the Cisco 2821 ISR. Looking at Cisco’s performance sheet, the Cisco 2821 ISR is only really designed to support lines of up to around 87 mbit.

So naturally, it was time to upgrade! Initially I wanted to get a faster Cisco router, but looking at the second generation ISRs, it’ll be a bit pricey!

I did actually upgrade all my 7204 VXRs to have NPE-400 modules, which according to the performance sheet should do around 215 mbits, but the 7204s are extremely loud, and I only switch them on when I am using them.

Michael and Jamie have always been talking about Mikrotik routers so I figured since Cisco is a no go, I’ll give Mikrotik a chance. I ended up buying two RouterBOARD 2011UAS-RM from WiFi Stock.

To put the RB-20011UAS-RM boxes in, I decided I was going to restructure my network a bit. I will be making a series of posts discussing my re-designed network.

My goals for the redesign were as follows:

  • The RB-2011UAS-RM boxes will only function as edge routers, encapsulating traffic in GRE tunnels, and that’s all.
  • There will be a link between both edge routers, with a BGP peering for redirecting traffic should one of my lines go down.
  • They will have GRE tunnels to all my dedicated servers/VPSs.
  • I will use Quagga on all dedicated servers, and VPSs outside my network to create BGP peerings with my edge routers.
  • I wanted to route all my internet out of a server I currently have hosted with Rapid Switch, so BGP on the RapidSwitch box (called diamond) will have to push down a default route.
  • I wanted to use my Cisco ASA 5505 Adaptive Security Appliance as firewalls between the edge routers and the core.
  • I recently bought a Cisco 2851 Integrated Services Router, which I will use as a “core” router.
  • I wanted as much redundancy as possible.

In my next post I will create a diagram of what I will be doing, and discussing the setup of the server I have hosted at RapidSwitch.

As I have never used Mikrotik routers before, I will also attempt to discuss my experiences of RouterOS so far as I go along.

  1. I am continuously in awe of your networking setup. I’ve definitely been going more down the OS & application side of things these days, need to setup a better networking lab and do some more playing with stuff to keep current.

  2. Haha, I’ve been dwelling on both sides to be honest, I wouldn’t be able to choose if someone told me I had to choose between networking or OS/application side of things. Lately at home, I’ve probably been concentrating more on networking though.
