Auto tunnel routing

Hello,

I have a project where a company has a main office and also has equipment at
a Co-Lo site. Their main office has two DSL lines (one for backup).
They have VPN tunnels between the sites: Main DSL to/from Co-Lo and Backup
DSL to/from Co-Lo. Currently, when we have a problem with the main DSL
going down, we have to change routes at both sites manually, and change them
back when it comes up.

Can I run quagga at both sites using the point-to-point VPNs, and have
quagga determine that the route is dead, and automatically change the
routes? Any particular VPN technology that you know works well with quagga,
or does not work well? CIPE, IPsec, OpenVPN?

I don't know, but Cisco manuals say that to run OSPF over a VPN
tunnel, you must use IPsec transport mode to secure a gre tunnel. I
think quagga also needs this, because quagga will want to run OSPF on
an interface, and at least on BSD IPsec tunnel mode is interfaceless.
