Re: [ns] Obtain routing table

[Andrea Josi <mr_josi@yahoo.it>]

Hi,

i have no experience with MPLS, so i don`t know if
there are problems with the interaction with DV,
anyway you could try defining a proc in your tcl
script, for instance:

proc mydump {} { 
 global ns 
 set now [$ns now] 
 puts "Routing table at time $now" 
 $ns dump-routelogic-nh 
 $ns dump-routelogic-distance 
} 


or

proc mydump2 {node fh} { 
 global ns 
 set now [$ns now] 
 puts "Routing table of node $node at time $now" 
 set dr [$node rtObject?]
 $dr dump-routes $fh
} 


"mydump" gives you the routing table of all nodes

"mydump2" gives you the routing table of a specified
node and writes the output on a file (fh)

you can get the routing table at several time instants
using lines such as


$ns at 3.1 "mydump"

or

$ns at 2.9 "mydump2 $n(2) $fh"

Cheers,
          Andrea.
