The AD assigned to the generated summary route (whether it is 5 or 100 or something else) does not have any impact on what is advertised to the neighbor on the interface with summary address configured. If you configure summary address 10.0.0.0 255.0.0.0 on an interface then that summary i...

FDof Best Route> AD of Second best Route FD>AD (Successor) EIGRP中,路由器会从拓朴表中选出去往特定目的地的最优路由,也称为successor路由,放入路由表,一旦最优路由down掉,EIGRP会马上从拓朴表中找出feasibel successor路由,将其升级为最优路由,并放入路由表,而不用经过计算,这样提高了收敛的速度。
