Description
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.
Please note: Students need to provide their own Windows-based laptops and 15-ft-or longer ethernet cables.Objectives
After completing this course, the student should be able to:
- 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 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
Prerequisites
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.
Who Should Attend
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
