OSPF virtual link experiment 1. Experimental environment: gns3,c6291 router II. Figure 3 of the experimental topology. In the experimental steps, we first configure the ip of R1. Then configure the ospf protocol and assign area. Then set up ip for R2, configure ospf protocol and assign are
After adding the third-party library to the scene, compile and run normally for a period of time, and then when the function is called, the above problem occurs. Replacing the HCCore.dll file alone cannot solve the problem. Through the version backtracking, all the dynamic libraries of the third party that the program depends on are updated again to solve the problem.
Service mesh is a new concept that has emerged in recent years. It can solve the problem of more and more complex communication between micro-services. So what is Service mesh? What specific functions does it have? What is its architecture? It is related to Kubernetes.

The "firewall" on the router interface-access control list, it is well known that there is a firewall on any system, which helps the computer / server network to build a relatively isolated protection barrier between its internal and external networks. a technology that protects the security of user data and information. And on the router,

1. Principle: the replica cluster sends a heartbeat every 2 seconds, and if it is not received after 10 seconds, it is marked as unreachable. MongoDB applies the database operation on the primary database and then records the operation in the operation log of the primary database. The auxiliary member then copies and applies these operations to the asynchronous process.
