router routing and network delay caused by the increase in packet forwarding efficiency.Routers: Traditionally, routers work on the third layer of the OSI layer Seven Protocol, whose main task is to receive packets from a network interface, and decide to forward to the next destination address based on the destination address contained therein. Therefore, the router first has to find its destination addres

Router (config) # hostname Router-Branch-23
In addition, you can configure a domain name on the router so that it knows which DNS domain it is in. Example:

NAT basic IP address conversion PrincipleIn general, the NAT address translation process is the conversion process between the "local address" and "Global Address", whether the packets are sent from the internal network to the external network, or from the external network to the internal network. The difference is that the network corresponding to the local address and global address is different, and the source and destination addresses of data pack
the sharing of data is slower than the original.
4, after sharing the local connection becomes a gateway. Other hosts want to surf the Internet are through this machine. As long as the other computer IP to the same network segment, IP not the same, the gateway to fill the top of the host IP can be online. Because the computer has become a network switch.

Generally, vrouters and firewalls are two different concepts, which can be understood literally. But now there are more and more vro functions. One of the most important functions is the security protection function. This is what we call the security router.
