ospf

My ISP has changed some stuff.  I'm seeing a lot of this in ipflog:

I read some stuff about ospf, and it seems that it would be nice to have
it working.  However, what I read was device specific (some Motorola
routers).  Is it possible to get this to work on OpenBSD?  If so how?
Pointers to a HOW-TO (preferably not too technical, I'm no network guru)
would suffice.

Thanks,
