Before a core network can provide advanced services and traffic engineering, it must first establish basic transport connectivity between its nodes. In this course, you will learn how interior routing protocols are used to establish dynamic routing within the core, how MPLS technology is used to enhance packet transport across the underlay, and how Segment Routing is changing the way we think about transport paths. In each module you will watch a brief video describing the underlying technology and then walk through a hands-on lab to dive deeper into the relevant protocols and configurations that make underlay routing work.

.Cisco's Routed Passive Optical Network (PON) solution differs from traditional PON solutions by having the Optical Line Terminal (OLT) exist as a pluggable transceiver in a router rather than a dedicated device. This learning path will cover the basics of how Cisco's Routed PON solution works and how to operate it.
