문제6

L is a network design engineer. In a certain network project, in order to reduce the complexity, the small L design network adopts a two-layer architecture, and the functions of the access layer are incorporated into the aggregation layer. In the design, considering that the core layer needs to have a fast convergence function, the aggregation layer performs route aggregation to reduce the number of routes. Which of the following routing protocols should L should use as the core layer routing protocol? (Choose one or more)

A. BGP

B. RIP-2

C. IS-IS

D. RIP-1

정답: C
