Category: BGP - CCNP SPROUTE

In this section you will find all BGP videos required for the CCNP SP (SPROUTE) 642-883 certification exam
  • BGP - INTRODUCTION (34:14)

    In this video we will provide an introduction to BGP, its philosophy and operation at a very high level. We'll see concepts like the mechanics of Path vector protocols, BGP conceptual differences with IGP's and an introduction to the use of attributes for routing.

  • BGP - MESSAGES (29:11)

    In this session we explore the different messages used by BGP to establish sessions, warn of possible errors, exchange information and keep up sessions. These messages are: OPEN, NOTICE, UPDATE and KEEPALIVE.

  • BGP - SESSIONS AND FSM (24:01)

    In this video we will see how sessions are established between two endpoints running BGP. Analyze the implications of using TCP as the transport protocol and the BGP Finite State Machine.

  • BGP - CISCO SESSION ESTABLISHMENT (01:06:00)

    This video will show you how to setup a session between two BGP neighbors on Cisco IOS devices. You will see the different commands to check the protocol status, the TCP-level implications, and how to solve common problems and troubleshooting procedures (with corresponding debugs).

  • BGP - CAPABILITIES (11:34)

    This video will show you what are the capabilities of BGP, how they are negotiated and represented in the BGP OPEN message. We will pay special attention to one of the most important capability: Multiprotocol Extension.

  • BGP - ATTRIBUTES (11:36)

    In this session we will explore the different types of attributes that BGP uses, we will see what are the characteristics and scope of each of them, along with some examples.

  • BGP - AS PATH (20:52)

    In this video we will look at how the autonomous systems numbers are structure, the operation of the AS-Path attribute, introduction to using private autonomous system number and the numbers of 4 bytes

  • BGP - 4 BYTE ASN SUPPORT (27:09)

    We will see in detail how the 4 bytes (32 bits) autonomous system numbers work, how this new numbering interact with systems that only support 2 bytes ASN and the operation of new capabilities, attributes, etc.

  • BGP - BEST PATH SELECTION ALGORITHM (22:32)

    In this video we explain the BGP decision algorithm. We will go through each of the path selection steps that the protocol takes to select which of the different paths received is the best.

  • BGP - CISCO IPV4 NLRI ADVERTISEMENTS (22:03)

    In this video we explore how we can create Network Layer Reachability Information of IPv4 networks. We will also see how we can modify the attributes of the advertisements with the network or redistribute commands in Cisco IOS.

  • BGP - IBGP SESSIONS (34:09)

    In this video we will explore how iBGP sessions work. We will focus on the implications of these sessions in terms of next-hop, the advertisements between iBGP sessions, the AS-Path management and synchronization.

  • BGP - CISCO IBGP SESSIONS (57:38)

    In this session we will see how we can check and configure iBGP sessions on Cisco IOS devices. We will see the implications of these sessions in the management of the Next-Hop, advertisements between iBGP routers and synchronization.

  • BGP - EBGP SESSIONS (31:48)

    In this video we will explore eBGP sessions, the controls that the protocols implements for session establishment, TTL considerations and Next-Hop management.

  • BGP - CISCO EBGP SESSIONS (47:34)

    In this chapter we will explore the configuration and verification procedures for eBGP sessions on Cisco equipment. We will focus in features like ttl-security settings, ebgp-multihop and disable-connected-check.

  • BGP - ROUTE REFLECTORS (24:45)

    In this video you'll see how route reflectors operate. We will also analyze in depth the function of the attributes that this functionality introduces, which are the Originator-ID and the Cluster-ID as well as some design implications.

  • BGP - CISCO ROUTE REFLECTORS (27:41)

    In this session we explore how we can configure and verify proper operation of BGP Route-Reflectors on Cisco IOS devices. We go into the details behind the operation of the Originator-ID and Cluster-ID used to stop any possible feedback loops.

  • BGP - CONFEDERATIONS (30:48)

    In this session we discuss in depth the operation of Confederations, which introduce attributes (focusing on the AS Confederation Set) and the different implications of using these mechanisms.

  • BGP - CISCO CONFEDERATIONS (44:17)

    Session dedicated to the configuration and verification procedures for BGP confederations in Cisco IOS devices.

  • BGP - AUTHENTICATION (14:41)

    In this video we will explore the different BGP authentication methods, concentrating on the authentication provided by the transport layer (TCP) using MD5 and its implications.

  • BGP - CISCO AUTHENTICATION (14:33)

    In this video we will explore how we can implement BGP MD5 authentication on Cisco IOS devices using the mechanism provided by TCP. Special attention is taken to the verification and troubleshooting procedures.
