routing table in order to support policy Routing, Linux uses multiple routing tables instead of one, and even without the use of Policy Routing, Linux uses two routing tables, one for upload to the local upper layer protocol and the other for forwarding. Linux uses multiple routing tables rather than one, so that the routing of different policies is stored in different tables, effectively exempted from the search for large routing tables, and improves the efficiency of searching in a certain d

Medium: If routing information published between Area2 and Area3 is allowed, a loop between regions will be formed.
To avoid inter-region loops, OSPF does not allow route information to be published directly between two non-backbone regions, but only within one region or between backbone and non-backbone regions. Therefore, each region's border router (ABR) must be connec

3.lsof-to list open filesIn many Linux or Unix-like systems, there are lsof commands, which are often used to display all open files and processes in the form of a list. Open files include disk files, network sockets, pipelines, devices, and processes. One of the main scenarios for using this command is when you cannot mount a disk and display an error message that you are using or opening a file. With this command, you can easily see which fi
