XIPV4R - Cisco IOS XR IPv4 Routing

Overview:

In this hands-on course, you'll get an advanced look at popular IPv4 routing protocols supported in Cisco IOS XR Software. Investigate 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 you in a detailed examination of the link-state database and the effects of virtually all protocol options. Explore the complexities of large-scale routing using the Border Gateway Protocol (BGP), with the focus placed on scaling networks using route reflection and confederations. You will also discuss and configure numerous BGP options, such as multihop, multipath, and authentication in a lab setting.

Agenda:

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 multiple 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.

Audience:

Technical professionals such as network operations center (NOC) engineers, network and senior engineers, and support engineers who design, implement, and operate IPv4 routing protocols in a service provider network consisting of routers running Cisco IOS XR Software.

Objectives:

• Basic unicast forwarding architecture and infrastructure
• Apply basic routing and forwarding security
• Examine bidirectional forwarding detection
• 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
• 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
