Based on the provided network topology exhibit, Router R2 is located within Autonomous System (AS) 100. To configure BGP parameters on this device, the administrator must first enter the BGP routing process mode using the router bgp 100 command. By default, the BGP path selection algorithm chooses only a single best path for a given destination. To instruct the BGP process to install multiple iBGP paths into the routing table to achieve load sharing, the maximum-paths ibgp <number> command must be issued. Since the engineer needs to distribute traffic across exactly three paths (towards R3, R4, and R5), the specific command required is maximum-paths ibgp 3.

B: The command ip load-sharing ibgp 3 is syntactically invalid in Cisco IOS for configuring BGP multipath capabilities.

D: The command router bgp 101 is incorrect because the exhibit explicitly illustrates Router R2 residing in AS 100, whereas AS 101 belongs to the remote eBGP domain.

E: ip load-sharing per-destination is an interface-level command used to dictate Cisco Express Forwarding (CEF) packet forwarding behavior, not the BGP routing process command required to install multiple routes.
