What is the difference between RIP and OSPF?

The main difference between RIP and OSPF is that RIP is a distance vector routing protocol that requires routing table updates at constant intervals while OSPF is a link-state routing protocol that sends updates only when it occurs. a change in the network.

RIP is a dynamic protocol that helps find the best path to send a packet from source to destination. It uses hop counting to determine the best route and to deliver packets in a short period of time. On the other hand, OSPF is a protocol that can replace RIP. A router detects a change in the network and sends the information to other routers so that they also have the same routing information.

What is R.I.P.

RIP stands for Routing Information Protocol . It is a dynamic routing protocol. It uses the hop count as the routing metric to determine the best path between the source and the destination to transmit the packet. Hop count refers to the number of routers between the source and the destination. The route with the least number of hops is the best route. RIP prevents routing loops by limiting the number of hops in a route. The maximum number of jumps is 15.

The RIP protocol updates the network constantly. Updates are always issued. There are three versions of RIP, and they are called RIP version 1, RIP version 2, and RIPNG.

RIP V1 – It is a classful routing protocol. It does not send mask information in its routing update; Send updates as a broadcast. Does not support update message authentication.

RIP V2 – It is a classless routing protocol. It does not send mask information in its routing update. Send updates as multicasts. In addition, it supports RIPv2 update message authentication.

RIPNG – Runs on IPv6 networks. Send updates as multicasts.

What is OSPF?

OSPF stands for Open Shortest Path First . It is a link-state routing protocol. It is a classless protocol and uses the Shortest Path First (SPF) algorithm to find the best path between source and destination. The routing table changes updates only if there is a change in the routers. In OSPF, there is no hop count restriction.

OSPF was developed by the Internet Engineering Task Force (IETF) as one of the Internal Gateway Protocol (IGP). It is designed to move packets within a large autonomous system. It uses the multicast address 224.0.0.5 for normal communication and uses 224.0.0.6 to update the Designated Router. Neighboring routers in OSPF must be present in the same area. They must have the same subnet mask. Also, the stub flag and authentication must be compatible.

Difference 

Definition

RIP is one of the oldest instance vector routing protocols that uses hop count as a routing metric. OSP is a routing protocol for Internet Protocol (IP) networks that uses a link-state routing (LSR) algorithm and falls under the Interior Gateway Protocol (OGP) group.

full form

The full form of RIP is Routing Information Protocol, while the full form of OSPF is Open Shortest Path First.

Type

RIP is a distance vector routing protocol while OSPF is a link state routing protocol. .

default metric

Another difference between RIP and OSPF is that RIP uses hop count while OSPF uses bandwidth.

hop count limit

RIP can have a maximum hop count of 15. OSPF provides an unlimited hop count.

Convergence

In RIP, convergence is slow, but convergence in OSPF is fast.

updating

Another difference between RIP and OSPF is that in RIP, the routing table is updated at constant intervals. But, in OSPF, the routing table is updated only if there is a change in the network.

multicast address

Also, RIP uses multicast address 224.0.0.9 while OSPF uses multicast address 224.0.0.5 and 224.0.0.6.

Complexity

While RIP is simple, OSPF is complex.

Use

There is also a difference between RIP and OSPF based on their usage. RIP is more suitable for smaller networks, while OSPF is more suitable for larger networks.

conclusion

The difference between RIP and OSPF is that RIP is a Distance Vector Routing Protocol that requires routing table updates at constant intervals, while OSPF is a Link State Routing Protocol that sends updates only when a change occurs. network.
