  • [ACP-DC Training #12] Virtual Routing and Forwarding (VRF)

    Virtual Routing and Forwarding (VRF) is an L3 (Network Layer) isolation technology used to build a Virtual Private Network (VPN). VRF isolates routing tables from other VPNs within the system and enables the use of redundant IP addresses. In other words, VRF is a technology that allows multiple routing table instances to coexist simultaneously within a single router. Each…

  • [ACP-DC Training #3] Data Center Technology

    Last time, we discussed the robust hardware products of data centers. While physical equipment such as servers, storage, and switches are important, what truly makes a data center 'smart' are the various technologies running on top of this hardware. Simply put, data center technology refers to the various protocols configured on switches. These protocols efficiently [manage] the applications and workflows that are the core of the data center…

  • [ACSA Training #33] Routing

    Since a switch is a Layer 2 device, its ports can only execute Layer 2 functions and protocols, such as becoming a member of each VLAN (member port) or transmitting frames. When an endpoint is connected to a port used as a Layer 2 interface, it forwards an L2 frame based on the destination Layer 2 MAC address. ※ AOS-CX switch ports are Layer… by default
