Enhanced interior gateway routing protocol eigrp, 90. It uses something called hop count to determinethe desirability or the distance to a destination network. Rip version 2 ripv2 is used for routing of ipv4 addresses in small networks. With the advent of ospf and isis, there are those who believe that rip is obsolete. Due to the deficiencies of the original rip specification, rip version 2 ripv2 was developed in 19934, published as rfc 1723 in 1994, and. Rip version1 is class full routing protocol and ripv2 is classless routing protocol. The cisco implementation of rip version 2 ripv2 supports plain text and message digest algorithm 5. Routing information protocol rip routing information protocol rip is a standardized distance vector protocol, designed for use on smaller networks. How to configure rip version 1 ripv1 sysnettech solutions. Configure, verify and troubleshoot ripv2 examcollection. Rip is one of the oldest distancevector routing protocols.
Routing information protocol rip protocol are the intradomain interior routing protocol which is based on distance vector routing and it is used inside an autonomous system. Configuring ip with md5 authentication for ripv2 and iprip delay on a frame. The routing metric is simply a calculationused by the router to determine which pathis the best path to a given network. The distance vector, hybrid and link state are the 3 types of the routing protocols. Rip prevents routing loops by implementing a limit on the number of hops allowed in a path from source to destination. The routing information protocol rip uses a single routing metric to measure the distance between the source and the destination network. Md5 authentication, route summarization, classless. The routing management protocol rmp based on the open shortest path first ospf algorithm provides routing of data units within the lec network and to external networks.
Unless ripv2 is manually specified, a cisco will default to ripv1 when configuring. The first column of routing table is destination address. Pdf performance analysis and redistribution among ripv2, eigrp. Cisco implementation of ripv2 supports two modes of authentication. Rip adheres to the following distance vector characteristics. The routing information protocol rip is one of the oldest distancevector routing protocols which employ the hop count as a routing metric. The routing information protocol rip is a distancevector,interior gateway igp routing protocol used by routers to exchange routing information.
In that, the distance vector routing algorithm will send the complete routing table and its information to neighbors. As you must have knownripv2 is a classless, distance vector routing protocol as defined in rfc 1723. Rip prevents routing loops by implementing a limit on the number of hops allowed in a path from the source to a destination. Hop count is the total number of routersthat the router must pass throughin order to reach the. Each hop in a path from the source to the destination is assigned a hopcount value, which is typically 1. A failsafe timer is required to delete stale routes, in case of routing protocol failure to. Configuration examples forrouting information protocol example. Configuring ripv2 is a pretty straightforward process. The routing information protocol rip is one of the oldest distancevector routing protocols. Im going to demonstrate how to use, or how to configurethe rip routing protocol. In the rip configuration mode, change the version of the protocol to 2 by using the version 2 command. Any flavor of rip running on a network transmits the entire routing table every 30 or 60 seconds by.
The original specification of rip, defined in rfc 1058, was. The main responsibility of any routing protocol is to populate the routing table, and so displaying the routing table is a good troubleshooting and verification approach. We can control the version of rip a particular interface will send or. A routing table is used in the memory of a router that. Sample configuration for authentication in ripv2 cisco. With the advent of ospf and isis, there are those who believe that rip is. Ripng rip next generation is a distancevector routing protocol for routing ipv6 addresses, as defined by.
The cost of metric in this protocol is hop count which is number of network which need to be passed to reach destination. Comparative analysis of the routing protocols ripv2, ospfv2 and. There are only three main differences between rip 1 and rip2. While it is true that the newer igp routing protocols are far superior to rip, rip. Comparison of rip, ospf and eigrp routing protocols based. Abstract this document specifies an extension of the routing information protocol rip, as defined in 1,2, to expand the amount. One of the main classes of routing algorithms is the distancevector algorithm. This document shows sample configurations for authenticating the routing information exchange process for routing information protocol version 2 ripv2. Some of these limitations have been addressed by the newer rip2 protocol specification.
The largest number of hops allowed for rip is 15, which limits the size of networks that rip can support. We want to include these subnets in the rip routing process. Being a classless routing protocol, means, it includes the subnet mask with the network addresses in its routing updates. The output here belongs to router a again and we can see all the entries or routes being learned via rip by looking at the first column. In this lab you will set up a network that utilizes rip as its routing protocol. Rip was one of the first true distance vector routing protocols, and is supported on a wide variety of systems. Ripv2 routing information protocol cisco community. The rip is the distance vector protocol type which has 2 version such as ripv1 and ripv2.
