This isn't a problem for my application (Ethernet neighbours in a DMZ
configuration), but it's good to have these figures anyway.

Good news! :-)
(An interesting thing that I found out is that, unlike HDLC keepalives,
the timers on boths ends to not have to be set to the same values - not
that there are specific reasons to *want* to have differing timers, but
in a multi-ISP-environment these things happen).
