R1 has 5 working interfaces, with EIGRP neighbors existing off each interface. R1 has routes for subnets 10.1.1.0/24, 10.1.2.0/24, and 10.1.3.0/24, with EIGRP integer metrics of roughly 1 million, 2 million, a nd 3 million, respectively. An engineer then adds the ip summary - address eigrp 1 10.1.0.0 255.255.0.0 command to interface Fa0/0. Which of the following is true?（）

A、R1 loses and then reestablishes neighborships with all neighbors.

B、R1 no longer advert ises 10.1.1.0/24 to neighbors connected to Fa0/0.

C、1 advertises a 10.1.0.0/16 route out Fa0/0, with metric of around 3 million (largest metric of component subnets).

D、R1 advertises a 10.1.0.0/16 route out Fa0/0,with metric of around 2 million (med ian metric of component subnets).
