The Advanced Routing and Switching for System Engineers (ARSFE) course helps learners to configure and monitor advanced routing and switching services in Cisco devices. The course starts with an overview of advanced technologies such as security, bandwidth and application optimization and quality of service (QoS) as implemented in Cisco devices. The main families of Cisco routers and switches are described with respect to their hardware and software characteristics. The course then focuses on some advanced aspects of network management, including secure management access (Secure Shell [SSH]) and network monitoring with Syslog, Network Time Protocol (NTP), and Netflow services. High availability on Layer 2 (EtherChannel and Rapid Spanning Tree [RSTP]) and on Layer 3 (Hot Standby Router Protocol [HSRP], Virtual Router Redundancy Protocol [VRRP], and Gateway Load Balancing Protocol [GLBP]) is presented through configuration examples, followed by description of hardware and software redundancy on high-end modular switches. The course concludes with extensive explanation of Multiprotocol Label Switching (MPLS) Virtual Private Networks (VPNs), with special attention to troubleshooting aspects of this technology.
