CCNP的self study有个很好的设计，就是实验环境比较统一。

这样的话，用dynamips（下称dy）这样的软件进行实验模拟是最好不过的了。

在此，我将自己写的dynagen的net文件放出，供有需要的朋友参考下载。

1、实验基准。按照CCNP-BSCI附录H（P651）制定。

2、分布式环境。分布在两台电脑上，硬件环境为P4 3.0 HT，1GRAM。IP地址为192.168.0.201；192.168.0.202。

3、环境分割。全网一共十二台设备，每个实体机六台。其中，路由器（包括帧中继交换机）采用C3745，HUB采用C3640（为什么不直接用dy的以太交换模拟，是因为考虑到自己模拟实际路由器更方便控制配置）

4、dy实体。推荐采用0.2.8RC2，现在dynagen发布的是RC1的版本，在测试的过程中发现长期闲置环境会造成handle crash的问题，所以推荐使用最新的dy版本。目前没发现有其他问题。

其余配置一律按照CCNP实验室环境标准构建。

在net文件中没有省略任何参数，所有未用的参数全部用#注明，同时附带说明，方便大家微调。

autostart = False # Should all devices be automatically started? true or false,defaults to true. Can be overridden on a per device basis
debug = 0 # Debug output level. Higher numbers produce increasing levels of verbosity. 0 means none (the default). 1 is the same as the -d command line switch
#model = 7200 # Set the default router model for all routers in this lab. Current options are 2610, 2611, 2620, 2621, 2610XM, 2620XM, 2621XM, 2650XM, 2651XM, 2691, 3620, 3640, 3660, 3725, 3745, or 7200
ghostios = true # Enable or disable IOS ghosting globally for this lab. Can be overridden at the device defaults sections, or the device sections. Defaults to False.
ghostsize = 128 # Manually tweak the amount of virtual ram allocated by the ghost image(s). Use of this option should never be necessary, because the ghost size is now automatically calculated.
sparsemem = False # Enable or disable sparse memory support globally for this lab
#idlemax = 1500 # Advanced manipulation of idlepc. Applies to all devices in this network.
#idlesleep = 30 # Advanced manipulation of idlepc. Applies to all devices in this network.
#oldidle = false # Setting this to true allows you to use pre-0.2.7-RC2 idlepc values. This disables direct jumps between JIT blocks (new to 0.2.7 RC2)
