With the development of the routing industry, the market demand is more extensive, but many users still do not understand the routing configuration issues. Here we mainly provide a comprehensive description of the Cisco router NAT configuration. More and more INTERNET resource sharing methods are available. In most cases, ddnleased lines are widely used with thei
Routers are packet forwarding devices that work in the third layer of the OSI Reference Model-the network layer. Routers implement network interconnection by forwarding packets. Although routers can support a variety of protocols (such as TCP/IP, ipx/spx, AppleTalk, etc.), most routers in China run TCP/IP protocol. Routers typically connect two or more logical ports identified by an IP subnet or Point-to-Point protocol, with at least one physical port.
The router determines the output port and t

In DHCP settings, we usually work with routers. Here we will introduce the debugging and settings of Cisco routers and DHCP. A company uses Cisco 3620 as the ios dhcp Server. the IP address of the fastethernet0 port connected to the Intranet is 192.168.1.4. The L2 Switch uses two Cisco 2950 and the L3 switch uses a Cisco

Vro is a commonly used network device. I believe everyone knows the importance of backing up the cisco router configuration file. Next we will introduce how to use the COPY command to back up the cisco router configuration file, and how to COPY and back up the cisco router
The VPN configuration of the Cisco router is not important for network security, but also makes the user more convenient during use. In this experiment, we use the Cisco 2600 router and the Cisco router VPN configuration to implement the blue campus. The networks between the
The command line port of a cisco router uses a hierarchical structure, which requires logging on to different modes to complete detailed configuration tasks. From a security perspective, cisco IOS divides EXEC sessions into USER mode and privileged mode.
Features of the USER mode:
In USER mode, only basic monitoring commands are allowed. In this mode, the
Huawei router and the same class Cisco router in the functional characteristics and configuration interface is completely consistent, some aspects also according to the needs of domestic users made a good improvement. For example, in English and Chinese can be switched configuration and debugging interface, so that users do not have to face a large pile of Englis
The Cisco router market is very good. Many people may not understand how the Cisco router solves the router IP configuration parameters. It does not matter. After reading this article, you will certainly have a lot of GAINS, I hope this article will teach you more things. For Cisco Routers running transparent bridging,
