OpenVPN tunnel on Mikrotik and two channels. How?

Question

linux

What I can’t understand is how to switch the lifted tunnel to the backup channel when the main one goes down.

Answer 1

And we cannot understand, because there is no information.

Answer 2

google to help, how to choose a defaultroute via route_distance (it was on habré, is on off. wiki)
1: reboot mikrotik when ping is lost to the current gateway
2: then the script at startup to select a defaultroute
3: launch vpn over all this
4: DO NOT USE GOTO!!
5: GOTO 1 is of
course a crutch, but at the moment the only working option. On core-level switches, it seems like you can only lay down interfaces, but it didn’t take off on my CRS-125-24g (vpn didn’t understand that the route had changed)

Answer 3

It is created on Mikrotik 2 ovpn-client on different ip and through tool \ netwatch you set up the inclusion of the first channel when its ip is available, and the inclusion of the second when it is not available.
/tool ​​netwatch;
add host= interval=10s
down-script="/interface ovpn-client set ovpn-mainoffice-eps1 disabled=yes ;
/interface ovpn-client set ovpn-mainoffice-eps2 disabled=no;"
up-script="/interface ovpn-client set_ovpn-mainoffice-eps2 disabled=yes;
/interface ovpn-client set ovpn-mainoffice-eps1 disabled=no;";
