Description

BGP can be used to perform PBR. To manipulate the best paths that are chosen by BGP, you need to understand the different attributes that BGP uses and how BGP selects the best path that is based on these attributes.
|n Where multiple paths exist between your network and ISP, you need to filter certain information during the exchange of BGP updates to influence the route selection or to enforce an administrative policy. To meet this requirement, you must use filters. The primary filtering tools include route maps and prefix lists. Also, an AS path list is a useful tool for influencing inbound BGP traffic. When BGP filtering is configured, it is important that you understand how you can force information propagation.
|n The global Internet routing infrastructure is largely built using BGP. The IPv6 Internet continues to use BGP, which has undergone modifications to support it. This extended BGP protocol, called MP-BGP, is capable of carrying a rich set of routing protocols, including IPv4 and IPv6, over a transport protocol, such as IPv4 or IPv6.
|n This course describes the configuration of BGP path selection process using BGP attributes. How to configure various BGP filtering mechanisms to control routing updates is also explained. Lastly how to configure BGP in an IPv6 environment is detailed.
