Network Bridge Function Introduction, Features And Applications

Routes are classified into three types: static route, dynamic route, and direct route.

In the method of manual input static routing, in order to solve the routing problem of the entire ip world, it is very weak in reality.

So, the experts thought of letting the router from the home, tell the near by router, who l am next to, who am next to, so that after the completion of a circle, the routing table is available based on this principle, dynamic routing is generated.

The simplest dynamic routing protocol is called RIP, which is called "distance vector protocol", and we currently use its upgraded version ip2. When we say that a routine protocol is simpler complex, one of the criteria is the complexity of the "routing comprehensive cost" algorithm situated by the routing protocol, and the path cost algorithm of pip2 is the simplest ones. In RiP2, routers send so-called "distance vector" information to neighboring routers [https://www.hdv-fiber.com/products/] every 30 seconds, and the routing table stores only the next hop address of the best path to the destination site.

RiP2 selects the best path based on the minimum router hop count For example, there are two routes between router A and router B. 0ne route passes through 10 routers [https://www.hdv-fiber.com/products/] and the other route passes through 8 routers [https://www.hdv-fiber.com/products/], Rip2 determines that the ip packet in A must pas through the second route to reach router BR! P2 allows a maximum of 15 hops, More than 15 hops are considered unreachable.The new ipv6.based Rlp protocol piPng has improved the information format and address related aspects than RlP2.

Simplicity is both a strength and a weakness. For a huge lP network only relying on the number of hops this distance: parameter to choose a route, in many cases will be a bit of a chore the same example, router A arrives at router B's path 1 with a seemingly arge number of hops, but if the bandwidth is much larger than that of path 2, what will Rlp2 do?

RIP2 will still stubbornly choose path 2. And in fact, Dath2 is not optimal, Therefore, RlP is suitable for smaller or at the edge of large lP networks.
