Junos Service Provider Switching

Duration : 2 Days (16 Hours)

Junos Service Provider Switching Course Overview:

This two-day course has been designed to provide students with intermediate-level knowledge of switching concepts and practical configuration experience. It covers a wide range of switching topics, including LANs, Layer 2 address learning, bridging, VLANs, provider bridging, VLAN translation, spanning-tree protocols, and Ethernet Operation, Administration, and Maintenance (OAM). Additionally, the course delves into the Junos operating system (OS)-specific implementations of integrated routing and bridging (IRB) interfaces, routing instances, virtual switches, load balancing, and port mirroring. It also introduces fundamental concepts such as the Multiple VLAN Registration Protocol (MVRP), link aggregation groups (LAGs), and multichassis LAG (MC-LAG).

This course is designed around Junos OS Release 22.1R1.10 and emphasizes hands-on learning through demonstrations and practical labs. Students will have the opportunity to configure and monitor Junos OS operations during these hands-on exercises, which will be conducted using MX Series 3D Ethernet Universal Edge Routers.
