Rip how many hops
Version number—Specifies the version of RIPng that the originating router is running. This is currently set to Version 1. The rest of the RIPng packet contains a list of routing table entries consisting of the following fields:. Route tag—A route attribute that must be advertised and redistributed with the route.

RIP Overview RIP is an interior gateway protocol IGP that uses a distance-vector algorithm to determine the best route to a destination, using the hop count as the metric. Distance-Vector Routing Protocols Distance-vector routing protocols transmit routing information that includes a distance vector, typically expressed as the number of hops to the destination.
Figure 1: Distance-Vector Protocol. Note: RIP is not supported for multipoint interfaces. Maximizing Hop Count The successful routing of traffic across a RIP network requires that every node in the network maintain the same view of the topology. Split Horizon and Poison Reverse Efficiency Techniques Because RIP functions by periodically flooding the entire routing table out to the network, it generates a lot of traffic.
Figure 2: Split Horizon Example. Figure 3: Poison Reverse Example. Limitations of Unidirectional Connectivity Because RIP processes routing information based solely on the receipt of routing table updates, it cannot ensure bidirectional connectivity. Figure 4: Limitations of Unidirectional Connectivity. RIPng has the following architectural limitations: The longest network path cannot exceed 15 hops assuming that each network, or hop, has a cost of 1.
The rest of the RIPng packet contains a list of routing table entries consisting of the following fields: Destination prefix—bit IPv6 address prefix for the destination. Prefix length—Number of significant bits in the prefix. Metric—Value of the metric advertised for the address. Supported IPv6 Standards. Accessing Standards Documents on the Internet. It can be statistical time division multiplexing and frequency division multiplexing. Before we Every channel has a specific In the rising technology, many people are dreamed of talking robots, flying rockets.

The path with the lowest hop count is considered as the best route to reach a network and therefore placed in the routing table. RIP prevents routing loops by limiting the number of hops allowed in a path from source and destination. The maximum hop count allowed for RIP is 15 and a hop count of 16 is considered as network unreachable.
Attention reader! Features of RIP : 1. Updates of the network are exchanged periodically. Updates routing information are always broadcast. Full routing tables are sent in updates. Routers always trust routing information received from neighbor routers. This is also known as Routing on rumours. Scroll down for the video and also text tutorials.
Neil, just wanted to say thank you and that you have another success story! The exam was not easy by any means — thank you for all of your hard work. You truly have a gift for teaching. Keep up the good work! RIP uses hop count as its metric.
So, let's say that router R1 wants to get to the Then, that network would be 3 hops away. A hop is a router that the traffic has to go through to get to that final destination. The maximum hop count is 15 and it is a bit of a scalability limitation with RIP, therefore, it's not really used except in lab or demo environments.
RIPv1 is a legacy protocol that is typically not used at all anymore. RIPv2 isn't used very often. RIPv1 really isn't used at all anymore, although, it is still supported on Cisco routers. You don't have to use classful networks with RIPv1. They all have to be the same.
RIPv1 updates are sent every 30 seconds as broadcast traffic, so everything that gets hit by the traffic in that subnet has to process it. RIPv2 uses multicast address With authentication, we can put a password on the router and both sides of the link, so they will not form an adjacency unless we both have the same matching password.
It gives us some bare security. Authentication is supported in all the modern routing protocols but it's not covered on the CCNA exam. It supports IPv6 networks. Then optionally, we're going to say version 2. We do want it to be running the latest version. To specify the interfaces that you want RIP to be running on and to be advertised, we use the network command.
