如果需要500台主机。选用的vlan10。它给的网络段应该是10.10.2.0/23—10.10.3.255/23。这里的主机位有2^9 ...

这么多地址刚刚好啊，完全可以用，
network 10.10.1.0 255.255.254.0
default-router 10.10.1.254
dns-server 202.103.96.68

给你两个东西，你看一下，一个是安装程序，一个视频

大虾你知道怎样保存GNS3上面的配置吗？我用了write，然后把它导出startup。加载的时候再导进去。但是好像我配置的VLAN。VTP这些都没有了。不过之前的那些链路trunk就还在。求解。。。

The VLAN configuration is stored in the vlan.dat file

when you restart your Router or you turn off the GNS3, the VLAN configuration is missing, why? Because all the VLAN information is save to file vlan.dat.

how to load the vlan.dat in my router when I  restart the GNS3?

So, this is the step to save the configuration :



LH-ROUTER#erase flash
Erasing the flash filesystem will remove all files! Continue? [confirm]
Erasing device… eeeeeeeeeeeeeeeeeeeeeeeeeeeeeeee …erased
Erase of flash: complete


LH-ROUTER#squeeze flash:
Squeeze operation may take a while. Continue? [confirm]
squeeze in progress…
Squeeze of flash complete

LH-ROUTER#conf t
Enter configuration commands, one per line. End with CNTL/Z.
K-ROUTER(config)#vtp file nvram:vlan.dat
Setting device to store VLAN database at filename nvram:vlan.dat.

LH-ROUTER(config)#do dir nvram:
Directory of nvram:/

124 -rw- 0 startup-config
125 —- 0 private-config
1 -rw- 600 vlan.dat

129016 bytes total (127940 bytes free)
LH-ROUTER(config)#

LH-ROUTER(config)#do wr mem
Building configuration…
[OK]

So, this is the step to save the configuration :

你这个问题答案应该是针对这个问题的吧
Switch(vlan)#exit
% not enough space on flash to store vlan database. trying squeeze…First create squeeze log by erasing the entire device

% error squeezing flash – (Missing or corrupted log)

Error on database apply 40: NV storage failure

Use ‘abort’ command to exit
我要的是保存配置，下次打开可以加载进去，你的方法试过了，没有用。。

问题解决了，原来我以前都不是用新建工程做的。用新建工程然后点那个保存nvram那个就可以的了。but thank you all the same。。
