如何把两个局域网连成一个？请高手帮忙现在有两台router分别连接上不同的ASDL，有各自不同的ip，两台router距离很近，各有6台电脑连在上面。
为了共享文件方便，希望把这12台电脑放到一个LAN里面？
请问：是不是可以把两台router连起来？有没有可能做一个虚拟的LAN，比如用vpn，但是速度和真正的LAN没有分别？请高手帮忙，多谢。
You need routers (to connect WAN points) and switches (to connect LANs)
The simplest way in home / Small office is to connect your two WAN point by a router, and router to the LAN.
Things need to be take care:
1. IGRP / EIGRP should be adopted if your two ADSL have unequal speed (Since only these two support unequal cost load balancing)
2. When you connect LAN segements together, better ensure no switching loop, or otherwise enable STP.
3. Take care when you config your edge router. If static routes are used, make use of polic routing to avoid possible link down.
More advance technology such as GLBP can be used to solve the problem
VPN is definitely resource consuming unless you got dedicated VPN concentrator/firewall.
