The correct answer is A: maximum-path. The maximum-paths command (A) in BGP enables load balancing by allowing BGP to install multiple equal-cost paths into the routing table simultaneously. By default, BGP only installs a single best path. When maximum-paths is configured (e.g., maximum-paths 4), BGP can select up to

Question

What feature can be used to enable BGP load balance manually?

Options

Amaximum-path
Bmaximum-prefix

Explanation

The maximum-paths command (A) in BGP enables load balancing by allowing BGP to install multiple equal-cost paths into the routing table simultaneously. By default, BGP only installs a single best path. When maximum-paths is configured (e.g., maximum-paths 4), BGP can select up to that number of paths and distribute traffic across them, effectively enabling multipath load balancing. This is a manual configuration that overrides BGP's default single-path behavior. The maximum-prefix command (B) serves an entirely different purpose - it limits the maximum number of prefixes that BGP will accept from a neighbor, acting as a protective measure to prevent routing table overflow from a misbehaving peer. It has nothing to do with load balancing.
