Routing - IGP, PfR
Routing is the process of selecting best paths in a network. In the past, the term routing was also used to mean forwarding network traffic among networks. However this latter function is much better described as simply forwarding. Routing is performed for many kinds of networks, including the telephone network (circuit switching), electronic data networks (such as the Internet), and transportation networks.
In packet switching networks, routing directs packet forwarding (the transit of logically addressed network packets from their source toward their ultimate destination) through intermediate nodes. Intermediate nodes are typically network hardware devices such as routers, bridges, gateways, firewalls, or switches.
Performance Routing (PfR) complements traditional routing technologies by using the intelligence of a Cisco IOS infrastructure to improve application performance and availability. PfR can select the best path for each application based upon advanced criteria such as, reachability, delay, loss, jitter, and mean opinion score (MOS).
PfR can also improve application availability by dynamically routing around network problems like black holes and brownouts that traditional IP routing may not detect. In addition, the intelligent load balancing capability of PfR can optimize path selection based on link use or circuit pricing.

This session covers various topics that help network engineers build flexible, robust fast converging networks using EIGRP, including load sharing, hierarchy, and aggregation. We will review routing design considerations for campus, data center, and WAN solutions.
This session provides techniques for preventing problems in EIGRP networks, and troubleshooting difficult EIGRP problems when they occur. This session is for network engineers using or considering EIGRP as an interior gateway protocol in their network. Attendees should understand EIGRP operation and theory and routing concepts.
This session covers the OSPF topics relevant for modern networks. The OSPF solutions in the session will be applicable to both Enterprise and SP environments. Basic routing and OSPFv2 knowledge is a per-requisite for this session.
This session covers the ISIS topics relevant for modern networks. The ISIS solutions in the session will be applicable to both Enterprise and SP environments. Basic routing and ISIS knowledge is a per-requisite for this session.
This session discusses those techniques in detail and provides some real examples along with troubleshooting steps. This session includes a review of the Link State Advertisement (LSA) types and troubleshooting commands.
This session explains the Next Generation of Cisco Performance Routing (PfRv3) technology. This session is for anyone who wants to understand and deploy Cisco IOS Performance Routing.
IP routing protocols, including EIGRP, IS-IS, OSPF, and BGP, are constantly being improved to provide better services and capabilities. This session will cover some of the most recent advances in the world of IP routing protocols, and future technology direction network engineers should be on the lookout for.
