In a Distance Vector protocol, “counting to infinity”:

A.
Calculates the time taken for a protocol to converge

B.
Checks to make sure the number of route entries do not exceed a set upper limit

C.
Counts the packets dropped during a routing loop

D.
Sets an upper limit for hop count, so that routing loops can be broken if this limit is reached

E.
Causes the router to enter an infinite loop and requires the router to be restarted
