sometimes it's hard to come up with a good name for a concept that isn't
used a whole lot. (there's also some not-so-great names for concepts
that are used a lot).

I didn't know that I'd put PIP/SIP into the HOWTO :-) I remember asking
people what they wanted them called, and no-one had any really good ideas,
so that's what I've been using myself.

The IPs on the outside of the directors, other than the VIP(s),
are not involved in the working of an LVS, and neither the LVS
administrator, nor the client needs to know about them.
During setup, you have to know which ethernet card is on
the outside of the director, and if you are using TP or
fwmarks to accept LVS packets (and not a VIP), then you
need to know the MAC of the ethernet card on the outside,
but AFAIK, the primary IP on the outside of the director
is not involved in LVS.
In case I've missed something, how
have these IPs become a part of your LVS?
Do you have suggestions as to their name?
(As their discoverer, your naming suggestions
will be given highest consideration when the LVS
nomenclature committee holds its next meeting.)
