首先先下载
http://www.ipflow.utc.fr/dynamips/dynamips-0.2.5-x86.bin
http://nchc.dl.sourceforge.net/sourceforge/dyna-gen/dynagen-0.6.0.tar.gz
http://www.tcpdump.org/release/libpcap-0.9.5.tar.gz 这3个文件到/root下
1.安装libpcap
tar -zxvf libpcap-0.9.5.tar.gz
。/configure
make
make install
2.复制/root/dynamips-0.2.5-x86.bin到/usr/local/bin/下
cp dynamips-0.2.5-x86.bin /usr/local/bin
ln -s dynamips-0.2.5-x86.bin dynamips
3.解压dynagen-0.6.0.tar.gz
tar -zxvf dynagen-0.6.0.tar.gz
cd /usr/local/bin/
ln -s /root/dynagen-0.6.0/dynagen dynagen

好了，这样就可以找个net文件来启动dynamips了，建议建个dynamips的文件夹，把dynamips，ios，net文件都放进去
启动dynamips：
nice dynamips -h 7200
启动控制台：
dynagen /root/dynamips/xxx.net
进入控制台，跟windos下就一模一样了。
获得idle_pc
dynamips -p 3600 -t 3620 /root/dynamips/xxx.bin（这里是3620的ios文件）。
等到进入到route>命令行后，按"ctrl+]"松开后按i，就可以获得很多idle_pc号，复制count最大的那个到net文件里就ok了。
至于网卡参数，把net文件中的nio_gen_eth：xxx改成nio_linux_eth：eth0就行了。
在控制台下启动路由器后，新开启一个终端，然后telnet 127.0.0.1 3001（这里是r1的端口号）就可以进入路由器。
