dynamips模拟三层交换网络环境
1,首先安装winpcpap 4.0再安装dynamips
2,进入dynamips目录,把下载的7200.bin放到images目录里面
3,配置或者下载itaa01.net这样的配置文件放到dynamips安装目录下
4,运行dynamips-start.cmd启动服务
5,再运行itaa01.net即可启动啦
启动后有二个窗口一个Dynagen控制台,一个Dynamips Server
Dynagen控制台命令列表:
list 列出所有的仿真路由器
start /all 启动一个仿真器
stop /all 停止一个仿真器

常用FAQ:
1,让仿真器连接物理网络哦:
运行Network device list.cmd找到如下字样:
rpcap://\Device\NPF_{23B9C4E0-001E-4342-9B97-FE5A347B9CCB} : Network adapter
'Realtek RTL8139 Family Fast Ethernet Adapter' on local host
修改xxx.net文件把以太接口的参数改为物理网卡:
f0/0 = NIO_gen_eth:\Device\NPF_{23B9C4E0-001E-4342-9B97-FE5A347B9CCB}
测试:
config t
int f0/0
ip address 192.168.1.253 255.255.255.0
no shutdown
ping 192.168.1.1(通过)^_^
2,模拟三层交换机(加个NM-16ESW模块)
-----------------------------------------
三层交换机模拟试验:
# Simple lab
autostart = true
model = 3660
[localhost]
[[3660]]
image = "\Program Files\Dynamips\images\c3660-is-mz.124-8.bin"
exec_area = 8
idlepc = 0x604b85e0
ram = 128
#slot5 = NM-16ESW
[[ROUTER SW1]]
slot1 = NM-16ESW
fa1/0 = NIO_gen_eth:\Device\NPF_{23B9C4E0-001E-4342-9B97-FE5A347B9CCB}
fa1/1 = NIO_gen_eth:\Device\NPF_{23B9C4E0-001E-4342-9B97-FE5A347B9CCB}
fa1/2 = R1 fa0/0
fa1/3 = R2 fa0/0
[[router R1]]
#model = 3640
[[router R2]]
#model = 3640
-------------------------------------------------------------
启动好后先测试:
SW1:
int fa1/0
no switchport (设成三层端口模式，不存取vlan,如果要存取vlan的话就必须是二层端口)
ip add 192.168.1.253 255.255.255.0
no shutdown
ip route 0.0.0.0 0.0.0.0 192.168.1.104
ping 192.168.1.1
ping 外网ip都通
SW1:
int fa1/2
no switchport
ip address 172.16.1.1 255.255.255.0
no shutdown
R1:
int fa0/0
ip address 172.16.1.2 255.255.255.0
no shutdown
互ping是通的ok
清配置:
int fa1/2
no ip address
no ip route 0.0.0.0 0.0.0.0 192.168.1.104
------------------------------------------------------------------------
配置基于端口的vlan划分实验:
fa1/0 vlan11 192.168.1.253
fa1/2 vlan12 192.168.2.1
fa1/3 vlan13 192.168.3.1
代理服务器ip:192.168.1.104 (Linux Proxy)

测试在:vlan 11上面的pc11测试，ping 192.168.1.253,192.168.2.1,192.168.3.1是否畅通
tracert -d 外网服务器，跟踪路由看看是否经过192.168.1.253,192.168.1.104
---------------- R1 ----------------------------
hostname PC12
show ip int brief

int f0/0
ip address 192.168.2.2 255.255.255.0
no shutdown
ip route 0.0.0.0 0.0.0.0 192.168.2.1
测试:ping 192.168.2.1通,192.168.1.116通,192.168.1.253通
------------------ R2 ---------------------------------
hostname pc13
show ip int brief

测试:ping 192.168.3.1通,192.168.1.116通,192.168.1.253通,192.168.2.2通
------------- Linux Proxy 设置---------------------------------------------------
开启nat:
echo 1 > /proc/sys/net/ipv4/ip_forward
iptables -t nat -A POSTROUTING -o eth0 -j MASQUERADE
配置到vlan间网络的路由:
ip route add 192.168.2.0/24 via 192.168.1.253
ip route add 192.168.3.0/24 via 192.168.1.253
或者:
route add -net 192.168.2.0 netmask 255.255.255.0 gateway 192.168.1.253
route -n看看应该有:
192.168.1.0
192.168.2.0
192.168.3.0的路由表了
ping 192.168.2.2
192.168.3.2
都通过
PC12,PC13测试192.168.1.104都过哈:)
PC12,PC13测试外网，通过^_^ GameOver
