    If you are asking about what is commonly called a “Road Warrior” configuration, where the client is roaming and the IP address is changing, but it needs to connect back to a central server which does have a static IP, then yes, it does work. It actually, works very well. The MikroTik wiki has some examples, here is one that I like:

  What’s your consulting rate?

  Thank you for the OSPF stuff. Clearest stuff on the net.

  Perhaps you could oblige me.

  We have a baseball diamond shaped network with two feeds to the internet, one to home base, and the other to second base. It is set out pretty much like your basic configuration in the first tutorial, except it forms a routed loop. There are other routers connected to the various bases, and some connections ‘shorting out’ parts of the diamond, for example a link from second directly to home, different from the second -> third -> home, or second -> first -> home. It is getting messy as
  we install wireless connections where we can and try to cross connect all of them.

  The goal has always been redundancy when things go down, and load balancing when we need to distribute the load. OSPF has been a bit of a bucking bronco, but it works.

  My problem has been two fold.

  1.) How do default routes work. We presently have them hard coded into each router as a static route, but clearly if an outgoing link fails along the default route, the sending router will not
  intelligently shift its default route to another link. Does OSPF take care of this transparently by changing the default route for us?

  2.) If both links are up, say from 2nd base to home, but we want the traffic to go out one of the links and not the other, (unless it is down) what is the standard way of telling OSPF this?

  3.) Is there a way to tell OSPF to take ‘the same route back to the customer’ that it used on
  the outgo, or is that meaningless?

  4.) When there are two equal routes to take to an end point, will OSPF load balance automatically, if so how do we STOP that.

  Pointers to RTFM are welcome.

  Your stuff is the clearest to date. If there is a better way to e-mail you than this public comment let me know.
