there are few ways to access a vro, further configuration is required to restrict further access to the vro. Most Cisco routers are still controlled through remote logon and do not adopt any encryption method. Communication Using Remote logon is transmitted in plain text, which easily exposes the logon password. Although CiscoIOS12.1 adopts the SSHl encryption method, there are still many problems. Before

Dynamic and robust routing is extremely important for Internet networks. Therefore, any network engineer who is first involved in this field must not only understand the concept of routing, but also be able to control it in a real environment. However, the products provided by high-end network equipment suppliers such as Cisco in the routing field are all over the world. This means that most people can only learn routes in school or laboratory environ

I. Network Environment: The company uses a 3500 series vswitch (with a specific model of 3548) to connect a Huawei 2621 vro to the vswitch and access the Internet through optical fiber cables of China Telecom. Because I forgot the password, I tried to crack it. 2. preparations: Because the entire work needs to be disconnected, after all, operations such as restarting the switch are involved, so the time is

Maybe many people do not know the actual application of the NetEye firewall and the Cisco router. Next we mainly analyze the security problems of the NetEye firewall and the Cisco router. Firewall has become a key part of enterprise network construction. However, many users think that there are already routers in the n

It is very important to know some common knowledge about CISCO routers. Here we mainly explain the CISCO router tutorial, which provides a detailed analysis from configuration to access methods. This document uses Cisco2620 as an example to describe how to configure the vro and remote access, this article discusses how to use the DHCP service function of the inte
