I’ve linked various nodes together via tunnels over fibre internet. These tunnels carry wug traffic and provide a shortcut for traffic between various nodes.
Nodes linked via Fibre Bacbkone
I’ve indicated these as a link on WiND of type other.
This effectively becomes a bit of everything:
- A backup link system
- Or shortcut for long links
You can see them in action here:
This works very similar to our service tunnels and tunnels to other wugs but is like a tunnel back to CTWUG. Service tunnels run on area 0.0.0.1 which means the don’t carry backbone traffic. These run in area 0.0.0.0 (backbone) so carry backbone traffic.
The internet links are all 100Mbit or more. We set OSPF cost to 10 for these links but may increase them to reduce traffic a bit.
These nodes are linked via a Tinc tunnel operating as a switch. Thus it is as if routers at puck, bath, skouperd and others are plugged into the same virtual switch and traffic (and OSPF routing) is freely flowing over this switch. So it’s not really ptp but “broadcast”.
Routing is done with quagga and this is all run on ubuntu machines or VMs.
Wired or wireless
This is something we can consider more (or less). One of the issues in my head is that we are Cape Town Wireless User Group, so not sure how much of this we want or not. It definitely has positive role to play. Just putting that out there for discussion.
