Configuring BGP on Cisco Routers v3.2

This set of lab exercises (lab bundle) contains all the exercises associated with the Configuring BGP on Cisco Routers (BGP 3.2) course. The lab exercises cover all aspects of BGP configuration, including:

  • Configuring simple BGP connectivity with a service provider
  • Influencing BGP route selection
  • Configuring BGP filtering mechanisms, including AS-path filters, prefix lists and weights
  • Configuration of a transit autonomous system
  • Configuration of BGP route reflectors and BGP confederations
  • Configuring advanced BGP features including Local Preference, AS-Path prepending, MED, BGP communities, peer groups, and route flap dampening

This set of lab exercises contains the following exercises:

Objectives

Upon finishing this set of exercises, you will be able to:
Configure BGP on the router connecting customer network and establish routing between customer network and the Internet

  • Announce IP prefixes assigned to the customer toward the Internet
  • Redistribute routes from IGP into BGP and control the route redistribution via a route-map
  • Configure and monitor BGP route aggregation, including suppression of more specific prefixes for selected aggregates
  • Configure a BGP router in a multi-homed customer environment
  • Configure a routing policy in a multi-homed network to give preference to routes announced from one ISP over the routes from the second ISP
  • Configure and monitor BGP filtering mechanisms, including AS-path filters and prefix lists
  • Influence BGP route selection with weights and monitor BGP route selection
  • Limit the maximum number of BGP routes received from a neighbor
  • Configure BGP peer groups
  • Use BGP soft reconfiguration and BGP route-refresh to implement non-disruptive changes in BGP policies
  • Configure IBGP full mesh in a transit AS and other associated BGP parameters
  • Configure and monitor redundant BGP route reflectors in one cluster and multiple BGP RR clusters in an IBGP backbone
  • Configure and monitor BGP confederation in a transit IBGP backbone
  • Configure default BGP Local Preference and change BGP local preference with a route-map
  • Configure AS-path prepending and influence return traffic flow with it
  • Configure BGP MED with a route-map
  • Configure BGP route selection influenced by BGP communities propagated across autonomous systems
  • Configure and monitor BGP Route Flap dampening

    Importance

    This lab bundle is highly recommended to students who attended the BGP training in the past and would like to refresh and consolidate their BGP configuration and troubleshooting skills. As part of the Configuring BGP on Cisco Routers (BGP) course these exercises support the Cisco Certified Internetworking Professional (CCIP) certification.

    Target Audience

    The course is targeted at pre- and post-sales technical support engineers who have to design and implement BGP-based networks.

    Prerequisite Knowledge

    To successfully complete this set of exercises, you need in-depth knowledge of Border Gateway Protocol (BGP) as well as skills in configuring and troubleshooting BGP on Cisco IOS. This knowledge is best gained by attending the Configuring BGP on Cisco Routers (BGP) course. In-depth understanding of generic IP routing features as gained by attending Building Scalable Cisco Internetworks (BSCI) course is also required.
