Total SPB training course description A comprehensive look at Service Provider Bridging (SPB) as standardised in 802.1aq. This SPB course starts with the problems in traditional switched networks then moves onto to how SPB solves these problems. As IS-IS is key to loop free topologies in SPB networks, this protocols is also studied. What will you learn Explain the benefits of SPB. Explain how SPB works. Explain the role of IS-IS in SPB. Integrate SPB into existing networks. Total SPB training course details Who will benefit: Technical staff working with Ethernet.
