[ns] NS: million nodes (SCALABILITY)

[Jeu George]

Hello All,
 I wanted to generate a topology that will generate a lot of node

set ns [new Simulator]

for {set i 0} {$i<10000} {incr i} {
    set n$i [$ns node]
}

I have a few questions regarding this

1) How many nodes can NS support
2) After creating this node i need to reference them
   Like I have now creating node n0 n1 n2 .. n10000
  
   Now I need to do link them like

$ns duplex-link $n0 $r1 100Mb 1ms DropTail
$ns duplex-link $n1 $r1 100Mb 1ms DropTail
$ns duplex-link $n2 $r1 100Mb 1ms DropTail
$ns duplex-link $n3 $r1 100Mb 1ms DropTail

I also need to write a loop for this like

for {set i 0} {$i< 10} {incr i} {
$ns duplex-link $n$i $r1 100Mb 1ms DropTail
}   

This DOESNOT work though. How do i do this? 
ANy idea??
