Question 3

Which of the following statements is true about the BGP aggregation function?

A. Since BGP supports CIDR, BGP auto-aggregation can automatically aggregate the routes existing in the routing table into routes with natural masks

B. When applying BGP manual aggregation, you can use the origin-polic parameter to change the origin attribute of the aggregated route for more flexible control.

C. There are two types of BGP aggregation: automatic aggregation and manual aggregation.

D. BGP manual aggregation can advertise aggregated routes and specific routes at the same time, or only select specific routes to generate aggregated routes.
