How are two BGP load balancing routes with the same attributes advertised to neighbors?

In a scenario where two BGP (Border Gateway Protocol) load balancing routes have the same attributes, both routes will be advertised to other BGP peers. BGP is designed to support load balancing by allowing multiple paths to a destination. When BGP detects that multiple paths are available and they share the same attributes, it treats them as equal candidates for forwarding traffic to a specific destination.

This characteristic of BGP enables the protocol to distribute traffic more effectively across multiple available paths, improving redundancy and potentially optimizing bandwidth utilization. As a result, sharing both routes with peers allows for better load balancing and enhances the resilience of network traffic by not relying solely on a single path.

The other answer options would imply a limitation or selection process that is not aligned with BGP's load balancing capabilities. For instance, claiming that one optimal route is selected for advertisement contradicts the fundamental principle of load balancing where multiple routes are actively used. By allowing the advertisement of both routes, BGP supports flexible path selection based on the individual preferences and configurations of neighboring routers.
