A Cisco router is a commonly used network device. But what is the storage type of a vro? We will give you a detailed introduction through this article, and hope to have a deeper understanding of Cisco routers after reading this article.Memory category:1: RAM: Random Access to memory, equivalent to computer memory2: ROM: read-only memory.

When I got up this morning to go to the forum, I saw a post. Ask how to solve the following problem? A Cisco three-tier switch divides 3 VLANsVLAN 2:IP 192.168.1.1 255.255.255.0 192.168.1.254 Network SegmentVLAN 3:IP 192.168.2.1 255.255.255.0 192.168.2.254VLAN 4 IP 192.168.3.1 255.255.255.0 192.168.3.254Each VLAN can communicate with each other.Now add 1 Cisco routes to achieve shared Internet accessCisco

China Mobile's GPRS network uses the APN method to connect to the GPRS device terminal and communicate with the server through the APN. The customer purchased the Cisco 2811 router, and the mobile company needed to pull the optical fiber through the E1 port, I spent more than 1000 RMB with an E1 module. mobile companies are doing very poorly, and optical fiber connectors are not provided at all. I also boug

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 example, R1 (config) # key chain key1 R1 (co

The following describes how to connect to a Cisco 2500 series router. In this section, assume that the router to be connected has received a basic configuration.Figure 1-6 shows the connection work that needs to be done after 2 5 0 1. Each vro has a console connection toolbox, including a Black r j-4 5 cable and a set of connectors. To connect to A Wy s e or othe

not encrypted during network transmission, strict control is required. For example, set a strong password, control the number of concurrent connections, strictly control the access address using the access list, and set user access control using AAA.8. We recommend that you use FTP instead of TFTP for iOS upgrade and backup and configuration file backup. For example:Router (config) # ip ftp Username blushinRouter (config) # ip ftp password 4tppa55w0rdRouter # copy startup-config ftp:9. Upgrade
