Load Sharing with the Loopback Address as a BGP Neighbor For additional information about load balance, refer to How Does Load Balance Work?. This document describes how to perform load sharing in different scenarios with the use of BGP. The incoming and outgoing traffic paths are derived either statically or with dynamic protocols such as:Įnhanced Interior Gateway Routing Protocol (EIGRP)īy default, Border Gateway Protocol (BGP) selects only a single best path and does not perform load balancing. If your network is live, ensure that you understand the potential impact of any command. All of the devices used in this document started with a cleared (default) configuration. The information in this document was created from the devices in a specific lab environment. This document is not restricted to specific software and hardware versions. Knowledge of BGP Best Path Selection Algorithm Prerequisites RequirementsĮnsure you meet these requirements before you attempt this configuration: This document describes load sharing, which allows a router to distribute the outgoing and incoming traffic among multiple paths.
