I set this up here and it works great.  I am currently at home so I
don't have the setup here, but I will post it when I get to work.  For
those of you who don't know what the advantage is, here goes...

If you set it up without the subsectioning and you allocate, say, 20 static
and 30 dynamic addresses, then these addresses are the 50 addresses after
the FastPath on the ethernet.  Thus you just lost 51 addresses and you
only have 254 to start with (class B network).  If you use subsectioning,
then the 51 addresses are used on a different subnet and only 1 is lost
on the ethernet.  This is especially important if the FP is placed on the
main backbone.

As far as Shiva goes, if they said that, maybe they should sell off
the rights to the FastPath before they kill off all their business.

Mike.
