When people think of wolves, one species usually comes to mind: the gray wolf. The gray wolf is the largest wolf and the basis of legends. According to National Geographic, the breed was almost hunted to extinction in the lower 48 states of the United States. Even now, few exist outside Alaska.
Routing Information Protocol (RIP) is a protocol that routers can use to exchange network topology information. It is characterized as an interior gateway protocol, and is typically used in small to medium-sized networks. A router running RIP sends the contents of its routing table to each of its adjacent routers every 30 seconds. When a route is removed from the routing table, it is flagged as unusable by the receiving routers after 180 seconds, and removed from their tables after an additional 120 seconds.
