Routing Switching and Virtual Lans Information Technology essay
With the Routing and Switching exam launched in mid-2016, Cisco made some much-needed changes to shift the certification away from topics covered in previous exams, such as frame relay, and focus more on modern routing and switching switching technologies. Some of the key changes included an additional emphasis on Access. This self-paced course is intended for experienced networking professionals with beginning to intermediate knowledge of routing and switching implementations in Junos. This course includes an overview of switching concepts and operations, Virtual LANs VLANs, the Spanning Tree Protocol STP. A virtual local area network VLAN is a type of LAN that increases the capabilities of a LAN and makes it more efficient. VLAN is basically a logical collection of network devices, and when a VLAN is created, a large broadcast domain is divided into smaller broadcast domains, that is, virtual LANs. VLANs that allow a single LAN to be used. A switch L is a type of router that uses hardware instead of software. An L, also called a routing switch, uses ASIC switching technology. This switch works at the network layer of the OSI model. The function of an L is to route the packet based on the logical address,information.
