Figure 1 Relationship between RA, RP, RC, and RCD 1 shows that the routing domain contains the routing domain and recursively defines the continuous hierarchical routing level.

the minimum number of steps in this column, and calculate the minimum value. The key part is to find the minimum number of steps in each row. The simplest and feasible method is to find the 1 with the smallest subscript to the right in binary search, and then find the 1 with the largest subscript to the left in binary search, in this way, the complexity O (N * m * log (M), CF time limit is very loose. My approach is to use O (N * m) Time to pre-process, calculate the first position on the left

Enhance Remote Management Security of Cisco routers through SSH (1)

port is 22. By using SSH, all transmitted data can be encrypted, which is not possible in the "man-in-the-middle" attack mode above, and can also prevent DNS and IP spoofing. In addition, it also has an additional advantage that the transmitted data is compressed, so it can speed up transmission. 3. SSH deployment Based on the above tests and SSH security features, it is necessary to use SSH instead of Telnet for security management of Cisco routers. Of course, to implement security management

Configure the CISCO router CHAP authentication configuration for PPP authentication

This article describes in detail how to configure PPP authentication and CHAP authentication, and provides the command line for configuration. You can learn about the configuration process through the instance. When configuring PPP verification, select PAP and CHAP. PAP is the user name and password for the plain text transfer, which is not secure. CHAP uses hash values for verification. Passwords are not transmitted online, so the security is high. CHAP certification is also the basic configura
