That's a hard question to answer because of the diversity of sites we have and user levels.
First off, we use EoIP to keep an old legacy layer 2 network running as we attrition people off to UBNT and onto our routed L3 network. So basically at most of our sites we have legacy gear + new gear and a router. We are tearing down legacy backhauls which are all part of this old layer 2 network and using the EoIP to tunnel the layer 2 traffic where it needs to go. The layer 2 traffic is riding on new UBNT links we are putting up.
So in a single sentence, we have bits and pieces of this massive layer 2 network sitting behind our routed sites and we are using the new UBNT links to move the layer 2 traffic via EoIP.
As for traffic. It varies as I stated. When you read this, remember that I have many EOIP tunnels and many backhaul links running OSPF. During peak hours (6p - 2a) I can see EoIP tunnel traffic anywhere from 6mbps to 20mbps. This traffic then hops onto the link running OSPF which is moving all our routed L3 traffic from whichever site. My UBNT links can see on average up to 40-50mbps during peak hours. As we approach our CORE location, two things happen:
1. All this legacy layer 2 traffic rides a dedicated RocketM5 link to our CORE router.
2. The routed traffic rides a dedicated AirFiber link to our CORE router.
Now, two more things to consider:
1. When the OSPF flaps it only affects our routed network customers (the majority).
2. The EoIP is flawless and never drops. EoIP only goes down if I lose a link or power at a site.
And to throw a curve ball into this whole mix, sometimes the OSPF flaps during off peak hours when hardly any traffic is moving across a link.
As for configuration. Here's a basic example with some items masked:
