[ns] setdest: how to avoid getting Destination Unreachables?

[Noor Asraf]

Using the setdest utility, is there a way to avoid getting
#Destination Unreachables: 54? I mean if I want to avoid this, how do
I choose my parameters? And it seems like the number of  Destination
Unreachables keep changing for the same parameter. I got 54, 61, 41
using the following command:

./setdest -n 10 -p 0 -s 1 -t 150 -x 1500 -y 300 > scen-a

If I want to be able to reach all destinations, how do I choose my
params? What's the significance of this? Because, when I print out the
route table using AODV, I see NRTE. Something to do with random number
seed, but even if that changes it should give the same result??

Thanks!
