An engineer has been told to create an implementation plan to influence the choice of best BGP route on a single router using the Weight featurE. The sole Enterprise Internet - connected router, Ent 1, has neighbor relationships with Routers ISP1 and ISP2, which reside inside two different ISPs. The goal is to prefer all routes learned from ISP1 over ISP2 using Weight.
Which of the following answers lists a configuration step that would not be usefu l for achieving these goals?（）
A. Configuring the neighbor weight command on Ent1.
B. Having the ISPs configure the neighbor route - map out command on ISP1 and ISP2, with the route map setting weight.
C. Configuring the set weight command inside a route map on Router Ent1.
D. Configuring a prefix list to match all class C networks.
