BGP Multipath Load Sharing is the feature used when a single router has two parallel BGP paths to the same ISP and the design goal is to install more than one eligible BGP path in the routing table. By default, BGP selects a single best path after evaluating path attributes such as weight, local preference, AS path, origin, MED, eBGP over iBGP, IGP metric to next hop, and tie breakers. When the competing paths are sufficiently equivalent and BGP multipath is enabled, Cisco IOS can install multiple BGP next hops for the same prefix and allow the forwarding plane to load share across both links. Multihop is used to establish BGP sessions to non-directly connected neighbors, not to load balance. Next-Hop Address Tracking improves convergence by tracking next-hop reachability, but it does not itself create load sharing. AS-path prepending intentionally makes a path less preferred for inbound traffic engineering. Therefore, the correct BGP feature for balancing outbound traffic across two links to the same ISP is Multipath Load Sharing.
