The correct answer is C. R4. In PIM sparse mode, it's possible to load-balance PIM joins between equal-cost next hops. Without the command set protocols pim join-load-balance, only one interface is used as the RPF interface towards the source ( or RP ). By adding this command, multiple equal cost next hops…

Explanation

In PIM sparse mode, it's possible to load-balance PIM joins between equal-cost next hops. Without the command set protocols pim join-load-balance, only one interface is used as the RPF interface towards the source ( or RP ). By adding this command, multiple equal cost next hops can be used on a per-S,G-by-S,G basis.
