multiple extended traceroute

Hello All, I am having an issue Running multiple extended traceroute commands at a time. We have a major change for summarizing and post checkout needs to trace public dns, to make sure we are taking the same path. Here is what I wanted to do

Traceroute source vlan 1

Traceroute source vlan 2 .... The list goes on for about more than 100 commands. When using putty, prompt returns after executing first command , but I wanted to capture atleast 10 commands at a time minimum to save my time. Any ideas? I Know to run tcl script for ping but not for traceroute.

Any help will be greatly appreciated.

One thing is sure that you have to take help of script anyway to run many commands with little efforts.

Unfortunately I do not know tcl script.

I am using below perl scripts for running multipe commands on routers/nodes.



use strict;
use Net::Telnet ;

my @cmd_list;

my $f1 = "command_list.txt";  ### Store command you want to run here in this file ###

open FILE1, "$f1" or die "Could not open file: $! \n";
@cmd_list = grep(/\S/, @cmd_list);
close FILE1;

my $session = new Net::Telnet (Timeout => 15,Prompt => '/#$/');
print "\n\n";

$session->open("node_name") ; ###  Need to change 'node_name' according to your router IP/hostname ###

$session->login('username', 'password');  ### Change credential accordingly ###

foreach $cmd (@cmd_list)  {
my @output=$session->cmd("$cmd");
print "@output";



Hope this helps
