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).
