Goodday,

Currently using tinc 1.0.24 on Debian 8.x, OVH datacentre, two servers same 
VRACK (ie. internal ethernet bridge/switched together).

I’m wanting to get a remote server connected to both the two OVH servers for 
fail-over reasons, but having access via both to the shared vRack segment as a 
switch mode. Thereby Essentially I’m creating a ethernet loop…


----------------------vRack
  |                |
Server1   Server2
 |               |
 RemoteServer

tinc create tun/tap on server1 & Server2. this then connects to OpenVSwitch 
bridge/switch that have on both servers the eth1 interfaces as ports to that 
bridge/switch.


Questions:

1) Does tinc support some STP to pick up this type of loops and block one 
interface/link?
 I guess not, especially after looking at Broadcast = no|direct|mst

YEs, I might have a very corner case need which I am doing as a temporary 
solution while waiting for the right solution, but the question then gets 
raised:

2) Is there anybody that did any type of HA for tinc when the one daemon fails 
to connect to the other or vice versa?
(I guess my next stop will be something like the Linux HA if I really want 
this, else I’ll just have to manually switch between the two servers, or switch 
one off while the other is on…)


3) ANything else I might’ve missed this late in the evening?

Hendrik
