Good!

Yes, I remember about TCP MD5.

What about choosing route using administrative distance of the protocol? Does
this feature exist in Open(BSD+BGPdOSPFd)? Is it possible OSPF and BGP to
inject same route into kernel, and kernel prefers the OSPF one until it
is present, and then switches to BGP? This is what we have in zebra, where
the zebra daemon performs this task - choosing between routes originated
from different protocols. Since OpenBSD doesn't have this intermediate
daemon, I guess they do the choosing process in kernel. Is this correct or
I mistake?
