Tinc OSPF involving bridge

[John Halfpenny]

Hi Everyone,

I have a routing situation where Tinc looks like it could come in extremely useful, but I have a query I hope someone can cast an eye on, as I'm unsure whether Tinc can help me here.

I currently have a Quagga OSPF linux router which connects LAN A to LAN B over the quickest available of two routes (both routes at both ends connect to Quagga boxes to prevent collisions).

One of the routes involves connecting over a wireless bridge (which can't be set to routed mode) and the other connects over a routed wireless connection.

i.e.

LAN A OSPF --- W/less (NOIP)  --- Wireless (NOIP) --- LAN B OSPF
           +-- W/less 1.1.1.1 --- W/less 1.1.1.2  --+

This is basically to allow redundancy of the NOIP wireless, which drops at the first hint of fog or mist. :-)

Is it possible to configure Tinc to connect over one of two possible routes like this?

And if so, is it also possible over a bridged connection which has no external IP address (by specifying the interface in the config file)?

I realise there are other ways to do this, but I'm hoping that my previous post regarding Tincs ability to hop across VPNs will allow the site at the end of the Wireless to connect to other external VPNs.

If you've had the patience to read this far, then thanks for any advice you can offer!

John
