[OZAPRS] New n-N VK7 suggested settings

[Tony Hunt]

Just because I mentioned that it was perhaps possible to trap the WIDE3-3
3-2 etc in the digis didnt mean I was sugesting it was a good idea.. Its a
Kludge and may work on different digis and may not and is bound to work
differently on different types of digis..

Ive seen the question more than once on here in regards to .. Is there
anywhere in VK that cant reach a Igate within 2 Hops ??

Scott has come back with some issues and seems to prefer WIDE3-3 in VK7..
While ate the same time is looking down the barrel of VK3 with the biggest
amount of traffic in the country..

I tend to think we are planning for a situation that will cause more
traffic
with this approach.. Why plan it to be a flop when I thought this was all
about getting it right and doing it just once instead of having to mess
about and do it again later..

This is all about the problems we are likely to have in the future as most
of the states dont seem to have imediate traffic issues now.. So as the
network gets more busy into the future why have a system in place like
WIDE3-3 which will be an overkill by this time..

I just can help but think it silly planning for a situation that needs to
be
throttled back from day 1 when we are supposed to be planning into a
future
that seems to sugest that we will have major traffic issues.. If we wont
have major traffic issues then this whole discussion is all alot of hot
air..

As a sugestion in areas like VK7 and parts of  VK4 (VK4RBM etc)  why not
use
WIDE2-2 and grab the WIDE2-1 or WIDE2-0 final frames and Preempt them
onwards from the digis using the prefered taylored paths specific to the
area and situation which you are trying to work around.. That way you can
taylor the Paths to 4 and even 5 hops if need be to get them to the Igate
..
Also as more digis and Igates come on line then you can resort to WIDE2-2
with no Preempt neeeded and fall into line with everywhere else.. So the
network can gradualy shrink back into Igate Zones for lack of a better
terminology.. The WIDE3-3 wont jump across to VK3 so much and propagate
too
far if you are not using it and it wont need to be trapped and stopped
anywhere either..
