Many users may not know the router configuration very well. Here we mainly introduce how to quickly complete the router configuration in the networking. There may be several manufacturers' devices in a network, this makes it difficult for network maintenance personnel. This requires the network administrator not only to learn more about the network, but also to sum up network maintenance experience. In the maintenance of Intel switches, the author sum

(or teams) have a very low level of customization requirements for the underlying network controls. ASI is better suited for applications that have been developing for some time, or for developing resource-rich teams, because often these teams (or their applications) have accumulated some experience, both on the product and on the technical. The complexity of requirements is high up at this time, and the demand for the bottom-line is more and more, at this time AFN is difficult to meet the dema

Vswitches and vrouters are quite common. So I have studied the secrets of networking vswitches and vro devices. I will share them with you here, hoping they will be useful to you. When talking about vswitches and vrouters, you cannot figure out what their respective functions are, and some cannot figure out the differences between them, especially in the context that various media have promoted the "routing" function of layer-3 switches. As a matter o
