Composing Dynamips's Net file.

When using Dynamips, you must create Net file.
This file has strict grammer. so you should note it.

★ Composing batch file.


1. R3660.cmd file compose (make anyway)

@echo off
cd temp     ← Path to repository of temporary files.
"..\dynagen.exe" ..\R3660.net     ← Path to Net file.


2. dynamips-start.cmd file compose

@echo off
rem Launch a local copy of dynamips
set dynamips=%CD%\dynamips.exe
cd temp
start /belownormal /B "Dynamips" "%dynamips%" -H 7200
start /belownormal /B "Dynamips" "%dynamips%" -H 7201     ← Second session, if you need
pause


Check for temporary folder, and should erase all of them before start virtual router.
