108 Chapter 3: Medium-Sized Routed Network Construction
Figure 3-13 Count-to-In?¬?nity Condition
Without countermeasures to stop this process, the distance vector of hop count increments each
time the routing update is broadcast to another router. This causes data packets to be sent through
the network because of incorrect information in the routing tables. The following sections cover
the countermeasures that distance vector routing protocols use to prevent routing loops from
running inde?¬?nitely.
