Course Overview

Duration: 4 days
XIPV4R - Cisco IOS XR Software Advanced IPv4 Routing for Service Providers v4.0.1 This intensive hands-on course provides Cisco service provider customers with an advanced look at popular IPv4 routing protocols supported in Cisco IOS® XR Software Release 4.0.1. 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 the student 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 using route reflection and confederations.

Who Should Attend

  • Network operations center (NOC) engineers
  • Network and senior engineers
  • Support engineers
