FAQ-What Are the Preferences of Routing Protocols?

Latest reply: Mar 3, 2016 22:15:19 1281 1 0 0

Different routing protocols including the static routing may learn different routes to the same destination, but not all these routes are optimal. At a certain moment, only one routing protocol determines the current route to a certain destination. Therefore, each of these routing protocols including the static routing has a preference. When multiple routing information sources are available, the route learned by the routing protocol with the highest preference is used. The smaller the default value, the higher the preference, as shown in Table 1.
