What is the administrative distance of RIP EIGRP and OSPF?

By default, OSPF has a default administrative distance of 110 and RIP has a default administrative distance of 120….Cisco.

Routing protocol Administrative distance
Routing Information Protocol (RIP) 120
Exterior Gateway Protocol (EGP) 140
On Demand Routing (ODR) 160
External EIGRP 170

What is difference between RIP EIGRP and OSPF?

EIGRP is based on DUAL (Diffusing Update Algorithm) while OSPF uses Dijkstra’s Shortest Path Algorithm with the major difference in how they calculate the shortest routing path.

What is the administrative distance of EIGRP?

This is because EIGRP routes have (by default) the administrative distance of 90, while RIP route have a higher administrative distance of 120.

What is the administrative distance of OSPF protocol?

Administrative Distance (AD) and Autonomous System (AS)

Route sources Default AD
Connected interface 0
OSPF 110
RIP 120

What is RIP and EIGRP?

RIP stands for Routing Information Protocol. EIGRP stands for Enhanced Interior Gateway Routing Protocol. 2. RIP works on Bellman Ford algorithm. EIGRP works on DUAL(Diffusing Update Algorithm) Algorithm.

What is difference between RIP and OSPF?

RIP works on Bellman Ford algorithm. OSPF works on Dijkstra algorithm. It is a Distance Vector protocol and it uses the distance or hops count to determine the transmission path. It is a link state protocol and it analyzes different sources like the speed, cost and path congestion while identifying the shortest path.

What is the EIGRP protocol?

Enhanced Interior Gateway Routing Protocol (EIGRP) is a network protocol that enables routers to exchange information more efficiently than earlier network protocols, such as Interior Gateway Routing Protocol (IGRP) or Border Gateway Protocol (BGP).

What is the difference between RIP and EIGRP?

RIP routing protocol creates two table in the router: Routing Table, and Topology Table. EIGRP routing protocol creates three table In the router: Neighbor Table, Topology Table, and Routing Table.


RIP, EIGRP and OSPF are all interior gateway protocols (IGP) while BGP is an exterior gateway protocol (EGP). Basically, interior protocols are meant to dynamically route data across a network that you fully control and maintain.

What is the Eigrp protocol?

What are the EIGRP States?

EIGRP sends out five different types of packets—hello, update, query, reply, and acknowledge (ACK)—that are used to establish the initial adjacency between neighbors and to keep the topology and routing tables current.

How do I redistribute OSPF to EIGRP?

Redistribute OSPF into EIGRP. First, we’ll redistribute OSPF into EIGRP. We do this under the EIGRP process: R2(config)#router eigrp 12. Let’s take a look at the redistribute ospf options: R2(config-router)#redistribute ospf? <1-65535> Process ID. We need to select the correct OSPF process. In our example, that’s process ID 1.

Why can’t I set routes in EIGRP for a redistributed route?

EIGRP uses five different variables to calculate the metric. However, redistributed routes do not have these parameters, which causes routes to not be set uniformly.

Which router is running EIGRP and OSPF?

Router B is running EIGRP with Router A, and OSPF with Router C. Router B is mutually redistributing between the EIGRP and OSPF processes. This is the pertinent configuration information for Router B:

What metrics does EIGRP use for redistribution?

EIGRP uses a metric that is based on bandwidth, delay, reliability, load, and MTU (even though MTU is not actually used in the calculation). Let’s check what options we have under the metric statement: First, I have to specify a bandwidth metric. In our topology, R2 is the only router doing redistribution.
