Course Details
Overview
The Cisco® Advanced Services Cisco IOS® XR Software IPv4 Routing (XIPV4R) for Service Providers Version 3.0 intensive, four-day hands-on course provides Cisco service provider customers with an advanced look at popular IPv4 routing protocols that are supported in Cisco IOS XR Software Release 5.1.1. The XIPV4R course investigates the intricacies of Interior Gateway Protocol (IGP) operation with Open Shortest Path First (OSPF) and Intermediate System to Intermediate System (IS-IS) protocol labs that engage you in a detailed examination of the routing database and the effects of many protocol options. The complexities of large-scale routing using the Border Gateway Protocol (BGP) are then explored with an emphasis on scaling large networks with route reflection and confederations.
