The other setup that has been put forward requires a central router and
all of us to be peering with the central router. We've heard arguments put
foward as to how the route reflector is a complex point of failure. It is
also true that we would be forcing multi-lateral agreement where
bi-laterals i.e one-one would do just as well. Besides which we all know
that all these routers will be holding will be in country routes thus a
route reflector may be over doing it. As well we know that the simpler
setup is cost effective. Every ISP simply uses their existing routers and
peers directly with the other ISPs. All that is needed in the centre is a
switch which the nsrc ( http://www.nsrc.org) has generously offered to
provide. All others who want service from the exchange simply connect
their routers to the switch and we peer with them.
	Therefore via cost it costs us much less, also as far as
people each ISP tech will take care of his end of the peering arrangement.
	Besides which, Randy who has tremendous experience in setting up
exchanges and peering arrangements and who knows all the models  quite
well says this is the way the rest of the world does it. I would imagine
that the rest of the world must have reasons why they do it the way they
do mayhaps they tried all these other setups and they did not work and
they ended up with the simpler model. I wouldn't like to reinvent the
wheel nor fail to learn from others experiences.
	Techies tend to like the more complex setups because their
complexity makes them sound more comforting and better. Yet in actual fact
the complex setups require complex solutions when they fail and it can
take days to isolate the cause of a problem. Yet for a simple setup
discovering what is wrong may actually be quite simple. Imagine something
went wrong would you much prefer to go rooting around wondering: is it the
central router?, the route reflector? or one of the ISPs' routers?
 Imagine one of the border routers was giving false routing information to
the centre this error would have a magnitude beyond that it would have if
we were having one-one perring arrangements.
