You want to use both links between R1 and R2. Because the two links have different bandwidths, you must ensure that they are used as fully as possible.

Which action accomplishes this objective?

Explanation

A routing policy that tags routes with the appropriate BGP link-bandwidth community enables weighted equal-cost multipath, so the higher-bandwidth path carries a proportionally greater share of traffic while both paths are used. This mechanism requires multipath and per-packet load balancing; per-prefix load balancing does not support the link-bandwidth attribute.
