    Course Details


    The Cisco¬ģ Advanced Services Cisco IOS¬ģ 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.


    Upon completing this course, the learner will be able to meet these overall objectives:

    • Describe the basic unicast forwarding architecture and infrastructure
    • Describe and apply basic routing and forwarding security
    • Describe and examine bidirectional forwarding detection
    • Explain nonstop forwarding operation
    • Configure Routing Policy Language (RPL) sets and policies
    • Design hierarchical and parameterized RPL policies
    • Configure IS-IS Level 1 and Level 2 areas and verify operation
    • Implement route redistribution and summarization in IS-IS
    • Configure a multiple-area OSPF domain and verify operation
    • Implement route redistribution with a route policy
    • Configure autonomous systems with BGP route reflectors and as a confederation
    • Configure external BGP between adjacent autonomous systems
    • Implement BGP neighbor-route policies
    • Examine internal and external BGP operation

    Lab Outline

    • Examining Cisco IOS XR Software Routing Infrastructure Start a static-routed configuration in both cores, and examine the routing environment
    • Routing Policy Language Design and configure a route policy to filter routes
    • Configuring IS-IS Routing Configure Core 2 routers as an IS-IS domain
    • Configuring OSPF Routing Configure Core 1 routers as a multiple area OSPF domain
    • Configuring BGP Routing Configure each core as a separate autonomous system running internal BGP (iBGP) and interconnected with external BGP (eBGP). Implement RPL route policies between autonomous systems


    This course is for technical professionals who design, implement, and operate IPv4 routing protocols in a service provider network consisting of routers running Cisco IOS XR Software.

    The following are considered the primary audience for this course:

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


    Following are the prerequisites for this course:

    • Knowledge of the Cisco IOS XR Software configuration syntax to the extent covered in the Cisco CRS-1 Essentials or Cisco XR12000 Series Essentials course.
    • Ability to establish, without assistance, a basic configuration for OSPF, IS-IS, and BGP as demonstrated in the Cisco CRS-1 Essentials or Cisco XR12000 Series Essentials course labs.
