Refer to the exhibit. An engineer must configure iBGP multipath load sharing across three paths. Which two commands must be run on router R2? (Choose two.)

The correct answer is A. router bgp 100 C. maximum-paths ibgp 3. Router R2 is inside AS 100 and has three iBGP paths (via R3, R4, R5) toward AS 101. To perform iBGP multipath across these three equal-cost paths, BGP must: Run the correct BGP process for AS 100 Allow installation of multiple iBGP paths in the routing table This is done with…

Explanation

Router R2 is inside AS 100 and has three iBGP paths (via R3, R4, R5) toward AS 101. To perform iBGP multipath across these three equal-cost paths, BGP must: Run the correct BGP process for AS 100 Allow installation of multiple iBGP paths in the routing table This is done with: maximum-paths ibgp 3 router bgp 100 - enters the BGP process for AS 100 (correct AS per diagram). maximum-paths ibgp 3 - tells BGP to keep up to 3 iBGP paths to the same destination, enabling CEF to load-share across them.
