Following are the prerequisites for this course.

• Students should have 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.
• Students attending this class should be able to establish, without assistance, a basic configuration for OSPF, IS-IS, and BGP as accomplished in the Cisco CRS-1 Essentials or Cisco XR12000 Series Essentials course labs.

To locate Cisco courses that cover the listed prerequisites, go to the Cisco Training & Events Webpage at www.cisco.com/web/learning/index.html.

This hands-on four-day course provides an advanced look at popular IPv4 routing protocols supported in Cisco® IOS® XR Software. The XIPV4R course investigates the intricacies of Interior Gateway Protocol (IGP) operation through 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 link-state database and the effects of virtually all protocol options. The complexities of large-scale routing using the Border Gateway Protocol (BGP) are then explored, with the focus placed on scaling networks using route reflection and confederations. In addition, numerous BGP options, such as multihop, multipath, and authentication, are discussed and configured in a lab setting.

• Implement route redistribrution and summarization in IS-IS.
• Implement RPL policies in IS-IS.
• Configure a multiple area OSPF domain and verify operation.
• Configure route redistribution filtered with an RPL policy.
• Configure autonomous systems with internal BGP full-mesh, route reflectors, and as a Confederation.
• Configure external BGP between adjacent autonomous systems.
• Examine internal and external BGP operation.

• IPv4 Routing Architecture and Infrastructure
• Routing Policy Language

Lab Outline

The lab outline is as follows:

• Lab 1: Examining Cisco IOS XR Software Routing Infrastructure Boot a static routed configuration and examine the routing infrastructure environment.
• Lab 2: Routing Policy Language Design and configure a route policy to filter routes.
• Lab 3: Configuring IS-IS Routing Configure a core of routers as an IS-IS domain.
• Lab 4: Configuring OSPF Routing Configure another core of routers as a multiiple area OSPF domain.
• Lab 5: Configuring BGP Routing Configure each core as a separate autonomous system with one as an internal BGP route reflector environment and the other as a BGP confederation.

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
