I have a MIKROTIK RouterBOARD RB2011UAS-2HnD-IN +Level 5 router and have searched for instructions on how to setup Open VPN. However I have not been able to find it.
Can anyone help me out on this.

Thanks,

Rob

Here is the link to the manual http://wiki.mikrotik.com/wiki/Manual:Interface/OVPN. There are also some examples on the Wiki and there is a ton of information in the forums.
