Routing information protocol updating algorithm

RIP comes in three versions: RIP version 1, RIP version 2, and RIPng.

This example shows a number of different paths that a message can take when leaving R1 and destined for R6. When configuring static routing, typically the engineer has a single path in mind to reach the destination.So, to configure a route from R1 to R6 using the path through R2 and R4, a static route would need to exist on R1, R2, and R4 for the forward trip (R1 To provide reachability to every destination that potentially exists in the network, the engineer would need to calculate the best paths for each destination initially, and then individually configure each route along each best path.In this two-part series, Sean Wilkins, co-author of CCNA Routing and Switching 200-120 Network Simulator, discusses current network routing protocols and methods for implementing them.This article covers the types of static versus dynamic routing protocols and the differences between them.It advertises a complete copy of its routing table every 30 seconds via all enabled interfaces.

Once a router receives an update from a neighbor, it places the update into the routing table (assuming that there are no conflicts).Loop management for distance vector routing protocols uses two different methods: poison reverse and split horizon.is used every time a new route is learned from a neighbor; when this happens, the router automatically sends a route advertisement back out the learned interface with an infinite metric.is built to deal with network changes automatically as the topology changes within the network, and are typically used on all other network types not previously mentioned.Let's visualize this with the topology shown in Figure 1.RIPng works similarly to RIP version 2, but for IPv6 addresses.
