Thanks for the response.. I did the following;

#!/usr/bin/perl
#
$template_file_name="rtr-template.txt";

open(OFILE, "> test") || die "output config file $ofile_name: $!\n";

while(<>) {
   
   ($location, $name, $lo0ip, $frameip, $framedlci, $eth0ip, $x) 
       = split (/,/);

   open(TFILE, "< $template_file_name") || die "config template file $
+template_file_name: $!\n";
   $ofile_name = $name . ".txt";
  

   while (<TFILE>) {

     s/##location##/$location/;
     s/##rtrname##/$name/;
     s/##eth0-ip##/$eth0ip/;
     s/##loop0-ip##/$lo0ip/;
     s/##frame-ip##/$frameip/;
     s/##frame-DLCI##/$framedlci/;

     printf OFILE $_;
   }
}

I tried just moving the line as is, but since $ofile_name hadn't been defined yet, that would't work.. so i replaced the variable with 'Test' This creates a file called Test with the information required.. however still only processes the first line of the CSV - as i guess is expected, as it is emulating the same problem as before.. If i move the line "$ofile_name = $name . ".txt";" to the top aswell, so it looks like:

#!/usr/bin/perl
#
$template_file_name="rtr-template.txt";
$ofile_name = $name . ".txt";
open(OFILE, "> test") || die "output config file $ofile_name: $!\n";

while(<>) {
   
   ($location, $name, $lo0ip, $frameip, $framedlci, $eth0ip, $x) 
       = split (/,/);

   open(TFILE, "< $template_file_name") || die "config template file $
+template_file_name: $!\n";

   while (<TFILE>) {

     s/##location##/$location/;
     s/##rtrname##/$name/;
     s/##eth0-ip##/$eth0ip/;
     s/##loop0-ip##/$lo0ip/;
     s/##frame-ip##/$frameip/;
     s/##frame-DLCI##/$framedlci/;

     printf OFILE $_;
   }
}
