from the Cisco2600 series, Cisco has adopted modular interfaces, some interface interfaces and network modules) the customer will purchase the product based on their own needs, which makes Cisco router products highly scalable. Cisco's Cisco2600 series routers have enterprise-level versatility, integration, and scalability. With the emergence of new enterprise a

---- GRE only provides encapsulation of data packets. It does not have encryption to prevent network listening and attacks. Therefore, in the actual environment, it often corresponds to an IP address.
When the SEC is used together, IPSec provides encryption of user data to provide users with better security.
The GRE protocol has two main purposes: internal protocol encapsulation and private address encapsulation. In China, CEN uses almost all TCP/IP protocols,
It is very important to know some questions about Cisco router configuration. So I have studied the detailed introduction of Cisco router configuration statements, and I will share them with you here, hoping to help you. Cisco routers once dominated enterprise wide area netw

At the same time, LinksysWRT320N starts from the user experience and works with the gorgeous and easy-to-use "Lela" software, which enables users to establish a wireless network within a few minutes, making applications and management very convenient.

There may be a lot of people who don't know about Cisco router configuration. Here we mainly analyze the Cisco router configuration commands. After reading this article, you will certainly have a lot of GAINS, I hope this article will teach you more things.

Cisco SDM is an intuitive and web-based device management tool for managing routers based on Cisco ios® software. Cisco SDM simplifies the router and security configuration process through the Smart Wizard, and with these wizards for customers and Cisco
robust firewall features. It supports WPA wireless security standards and can use 128-bit WEP encryption to encrypt all wireless transmission data. With a powerful status packet detection SPI (SPI) firewall, This router can protect computers from most Internet attacks. Similarly, once powered on, it can work with a network cable. We don't need to configure too much. It also supports the VPN passthrough fun
For Cisco router authentication, when performing the cisco Route Selection protocol (r12002; VPN) authentication, the key is irrelevant to the key ID when using plain text (General authentication, during MD5 authentication, the key and key ID are related, that is, the key IDs and keys at both ends must be the same, for

Default route Configuration
The default route is generally used in the stub network, and the stub network is a network with only one egress path. Use the default route to send packets that are not included in the route table of the target network. In fact, you can understand the default route as a static route with a wildcard (wildcard.
