NettetRouting loops occur when a packet is continually routed through the same routers over and over again, in an endless circle. Because they can render a network unusable, distance vector routing protocols (such as RIP and EIGRP) employ several different mechanisms to prevent routing loops. We will describe them in this article. Split Horizon Nettet4. mai 2014 · Open the Microsoft 365 admin center, and then click Admin centers > Exchange (you might need to click ...show all first).
