[quagga-users 14747] Re: Problem with Init/DROther

I've changed the mtu size of my ovpn config to 1440 and added fragment 1400 on client and server, but without any help.
Problems is not solved. I was thinking about the fact that i do have only interfaces that could be shutdown. From my CCNA i have an clue that it could be nessesary to have an lo0 interface in the ospf process that can not be shutdowned ?

One problem that can cause this is MTU blackhole (1500 byte packets are dropped, for instance 1480 or 1460 packets are not).

Try adding "fragment 1400" to your OpenVPN configuration and see if that helps.
