Sammanfattning The Cisco IS-IS Configuration Course course (ISIS) will focus on Cisco Systems' implementation of the OSI IS-IS routing protocol. The course offers an opportunity to explore the theory and application of IS-IS in the context of enterprise internetworking and the role IS-IS will play in Multi-Protocol Label Switching (MPLS).
Candidates will be able to apply this knowledge towards developing better internetwork design and obtaining Cisco career certifications.
Förkunskaper
