ospf and eigrp configuration

A. router eigrp 11. First, create a network topology for EIGRP as in the image below. OSPF Why is EIGRP called Distance Vector? RIP is configured between R1-R4 and OSPF configured between R3-R4. With which network type will OSPF … End with CNTL/Z. It Is a Industry standard dynamic routing protocol. The configuration for each router must be something like the following code: R1#conf t. Enter configuration commands, one per line. In this lab, you will configure redistribution from OSPF into EIGRP for IPv4 and IPv6, and redistribution of EIGRP into OSPF for IPv4 and IPv6. However the command behavior varies from o­ne protocol to another. Configuration Example: Route Redistribution for IPv6 Figure 4-4 shows the network topology for the configuration that follows, which demonstrates how to configure single point two-way basic redistribution between EIGRP and OSPF for IPv6, using the commands covered in this chapter. Today's post will discuss configuring authentication on routers for Routing Protocols Authentication . Configuration is as simple as defining the OSPF process using the router ospf command and then identifying the networks that will participate in OSPF routing. Redistribute OSPF into EIGRP. If we enter the network 10.0.0.0 command under the EIGRP configuration mode, both subnets will be included in EIGRP process because we’ve used a classful network number in the network command. In this case, the tag chosen is based on the EIGRP domain’s AS (process) number (it could be any unique value, however). EIGRP Enhanced Interior Gateway Routing Protocol) is Cisco's proprietary routing protocol based on Diffusing Update Algorithm. Router A and B have an OSPF neighbor relationship with BFD enabled. However, this is the only clear advantage of OSPF over EIGRP. EIGRP Is derived from Integrated Gateway Routing Protocol. The protocol was designed by Cisco Systems as a proprietary protocol, available only on Cisco routers. R1 (config)#router ospf ? Preliminary configuration: Configure all interfaces and the Frame Relay connection. Introduction of MPLS. It's time for the exciting part of our Enhanced Interior Gateway Routing Protocol, or EIGRP, discussion, configuration. RIP and IGRP also support the default-metric command. Packet is sent from Spoke1 to Spoke2 network via Hub (according to routing table) Spoke1 has this prefix via HUB tunnel IP for which has also NHRP static mapping. Upon completing this task, you should be able to ping both loopback interface addresses of each others. I started creating a key-chain and trying to apply it. This tutorial is the fourth part of this article. Learn EIGRP configuration commands, EIGRP show commands, EIGRP network configuration (with & without wildcards) and EIGRP routing (classful & classless) in detail. Verification. Take a look at R3’s configuration; this is where all the action is. a. Note:this would reset and renogotiate OSPF . A Sham links is required only between two VPN sites that belong to the same area and have a backdoor link for backup purposes. 13-4 EIGRP for IPv6. Redistribution from OSPF (process 1) Router(config-router)#redistribute ospf 1. Router#config terminal. And let's ensure that HQ has the ability to route to the 10.1.1.0/24 network and branch, and send traffic over to 172.16.1.0/24. R1#configure terminal. Router 1 (OSPF) router ospf 100 log-adjacency-changes network 0.0.0.0 255.255.255.255 area 0. However, this is not enough to exchange information between the two routing protocols. Answer: EIGRP does support secondary address. We will use this number with “router eigrp” command. R3(config)# EIGRP sumariza en la interfaz y OSPF lo hace desde ospfStep 6: Configure mutual redistribution between OSPF and EIGRP.Notice that R2 is the only router with knowledge of all routes (EIGRP and OSPF) in the topology at this point, because it is involved with both routing protocols. Therefore our redistribute command will be like this: R4 (config)#router eigrp 1. OSPF has it's own rules (area 0, filtering/summarizing only on abrs, etc.) The RID is chosen as the time the OSPF process is initialized. This behavior stops both outgoing and incoming routing updates. In this case we need to configure like this: Many routing protocols support authentication like OSPF, EIGRP, ISIS, BGP, and RIPv2. Cisco designed the new EIGRPv6 (EIGRP for IPv6) to be almost identical to EIGRPv4 (EIGRP for IPv4). OSPF is an internal routing protocol. The EIGRP protocol operates by making routing decisions Run the GNS3 network simulator software and then create a new project. Here, OSPF is enabled on a per-interface basis. Unlike OSPF, we must specify five metrics when redistributing into EIGRP: bandwidth, delay, reliability, load, and MTU, respectively. Router(config-router)#summary-address 172.16.32.0 255.255.224.0. However, the capability of EIGRP and OSPF to learn the dynamic routes for the network is functionally equivalent, but there are several differences between them. The Pros and Cons of OSPF and EIGRP. In the above command I have told OSPF to redistribute EIGRP routes from AS 1 with a metric of 10, which is lower than the OSPF default of 20. 3.EIGRP is Less scalable than OSPF. Q1. Enhanced Interior Gateway Routing Protocol (EIGRP) configuration in Router01. This tutorial explains how to configure EIGRP Routing protocol in Cisco Routers step by step with practical example in packet tracer. NETWORK ANALYSIS 1. Open shortest path first (OSPF) Open Shortest Path First (OSPF) is an active routing protocol used in internet protocol. Info and Configuration of OSPF & EIGRPThings to Remember about Link State Routing Link state protocols advertise a large amount of topological information about the network (tells what every metric is for every link in the network) Routers must calculate the metric (using Shortest path First Algorithm) Routers perform CPU intensive … It allows a router to use an autonomous system to share information it holds about the network and calculate the shortest path to a network. Switch(config-if)switchport trunk allow vlan 10,20,30 3.1.2 Routing protocols Routing protocol OSPF is used to communicate among the routers.The routing protocol is configured as below. Configure EIGRP AS 10 for Company A. Configure OSPF 10 for Company B. Configure OSPF router ID’s for Company B. You may also like: How to redistribute static routes into eigrp using Cisco Packet Tracer. <1-65535> Process ID. Router(config)router ospf 1 Router(config-router)network 101.0.0.0 0.0.255.255 area 1 Solved examples with detailed answer description, explanation are given and it would be easy to understand. Redistribution Configuration Syntax and Examples. After entering the EIGRP Configuration Mode, a network administrator's most common task is to specify which networks EIGRP will advertise. distance ospf { [intra-area dist1] [inter-area dist2] [external dist3]} (Optional) Sets the distance for all routes within an area. Protocols include IPX, AppleTalk and IPv6. The R1 dead timer expires between hello packets from R2. R2(config-if)# ip address 10.0.0.2 255.255.255.0 R2(config-if)# ip ospf 1 area 0. Following configuration shows the redistribution information into EIGRP from other routing protocols: First, get into the routing process configuration: Router(config)#router eigrp 100. That's how you can get EIGRP & OSPF to "talk" with each other, because one or more routers will run both protocols. General Terms Routing Protocols, internetworking. Govanet1(config-router)#redistribute eigrp 25 metric 2 . 2. Note that you can configure and enable two routing protocols on a router (e.g both OSPF and EIGRP). Example 5-18 shows how to configure the OSPF domain ID. Use the highest IP address of any up/up non-loopback interface. R3(config)# router ospf 1. After redistribute eigrp into ospf configuration, i m not able to ping eigrp network 10.1.1.1 and 1.1.1.1 which on R1 from R3 but i can able see the OE2 routes on R3, this is small topology, Can anyone help me on this? show ip ospf neighbor. Also, the administrative-distance of OSPF is made higher to 200 or above. Unequal cost paths are the different paths to a destination network with different metric values.… As you know from Chapter 2, summary routes can be used to group together various contiguous networks into a single route. OSPF stands For Open shortest path First. It is the first step in configuring EIGRP on a router as done here on R1: R1>enable. The Enhanced Interior Gateway Routing Protocol (EIGRP) is a Cisco Proprietary distance vector routing protocol [15]. Now R2 (and R1) will use which route to go to 172.16.100.1? Authentication—Plain text and message-digest algorithm 5 (MD5) authentication among neighboring routers within an area is supported. End with CNTL/Z. Figure 7-32 Flowchart for Troubleshooting EIGRP Redistribution Problem. 7.3.4 OSPF Command List Configuring OSPF is a lot like configuring RIP and EIGRP. If the DR fails, the new DR will be router B. In this tutorial we will learn how to configure Route Redistribution between OSPF and EIGRP using Cisco Packet Tracer.I have made a step wise tutorial showing redistribution process between EIGRP and OSPF and also performed Network connection Testing after Configuration.If you are preparing for CCNP Certification this lab will help you score and learn Route distribution Questions. route-map EIGRP-TO-OSPF deny 30 (deny a access list) match ip address 3. route-map EIGRP-TO-OSPF 40 ( this is a match all) set metric 300 set tag 30. verify. show ip route 10.4.2.0. However, this is not enough to exchange information between the two routing protocols. It is used to share the information from one router to the neighbour routers if they exist in the same region. 1. Though IGRP/EIGRP use only bandwidth and delay by default to compute the metric, it is still necessary to specify all five metrics when redistributing. Configure EIGRP authentication between both router. This is an advantage over Enhanced Interior Gateway Protocol, which is a proprietary standard from Cisco. Enhanced Interior Gateway Routing Protocol (EIGRP) is an advanced distance-vector routing protocol that is used on a computer network for automating routing decisions and configuration. OSPF routers need to establish a neighbor relationship before exchanging routing updates. interfaces are involved in both routing protocol OSPF and EIGRP. OSPF Configuration Step by Step Guide. show route-map. DC1 & 2 OSPF configuration: Router OSPF 10. IMPLEMENTATION This work is divided into three scenarios. EIGRP routers or switches send Hello packets to each other to form neighbors. R1 (config)#. 2. Not only do they support VLSM and manual route summarization, they both keep backup routes with ospf going the extreme by keeping all available routes to a destination. Passive-interface command is used in all routing protocols to disable sending updates out from a specific interface. Configure all Loopback interfaces on each router. Step 3. In a broadcast network, EIGRP sets up a full mesh adjacency relationship with each other, the routers exchange information with other. To configure OSPF the first step is to create an OSPF routing instance. Configuring OSPF Domain ID So I wanted to pull quick from the last lab quickly the two pieces of setup already done on the equipment from the last post: router consumes lesser power when running on EIGRP than when it runs on OSPF. If you’ve completed Lab 10-2 – Configuring Mutual OSPF and RIP Redistribution and Lab 10-3 – Configuring Mutual OSPF and EIGRP Redistribution then you should be no stranger to mutual route redistribution.. RouterB(config)# router eigrp 15 RouterB(config-router)# redistribute ospf 20 RouterB(config-router)# default-metric 10000 1000 255 1 1500 RIP and IGRP also support the default-metric command. Step 6: Configure mutual redistribution between OSPF and EIGRP. Let's setup EIGRP on our branch router and our HQ router. protocols (e.g. Ospf and eigrp concepts and configuration 1. INTRODUCTION EIGRP is a Cisco proprietary distance-vector protocol based Notice that R2 is the only router with knowledge of all routes (EIGRP and OSPF) in the topology at this point, because it is involved with both routing protocols. Next you will redistribute the EIGRP routes into OSPF and the OSPF routes into EIGRP. Unlike EIGRP, the wildcard mask in OSPF is required. R1—R2—R3, R1 configuration interface Loopback0 ip address 10.1.1.1 255.255.255.0! Please refer the beginning of this lesson to view the Enhanced Interior Gateway Routing Protocol (EIGRP) configuration IOS command. The OSPF network command uses a combination of network-address and wildcard-mask similar to that which can be used by EIGRP. As far as redistributing the routes I don't remember the commands (I just got my CCNA 2 weeks ago so I am still quite a newbie) would it be router ospf 1 redistribute eigrp 1 and vice versa? 2.It is quite easy to configure EIGRP while OSPF configuration is little bit Complicated. It reduces the workload that the router has to deal with as well as the volume of data which is being transmitted. 37. Router A will become the DR and router D will become the BDR. EIGRP Configuration. show ip route ospf. Open Shortest Path First (OSPF) is an interior gateway routing protocol developed for IP networks based on the shortest path first or link-state algorithm originated by Edgars Djikstra. OSPF and EIGRP Concepts and Configuration Things to Remember about Link State Routing Link state protocols advertise a large amount of topological information about the network (tells what every metric is for every link in the network) Passive Interface (RIP,OSPF and EIGRP) explained with interview questions. EIGRP stands for Enhanced Interior Gateway Routing Protocol. 5.OSPF only Consider or check Bandwidth while calculating optimal path but EIGRP consider Bandwidth as well as delay time,load ,reliability. 1. Neighbor Authentication. Also read: Best Network Mapping Tools & Software for 2021 OSPF routes can be exported into EGP and BGP. Learn OSPF configuration commands, OSPF show commands, OSPF network configuration (Process ID, Network ID, Wild card mask and Area number) and OSPF routing in … Lab 8 - OSPF and EIGRP Objective: To study OSPF and EIGRP Equipment: Packet Tracer Network Diagram: 10.10.10.2 255.255.255.0 1941 Router 10.10.20.2 255.255.255.0 10.10.10.1 255.255.255.0 10.10.20.1 255.255.255.0 1941 Routers 1941 Router2 Part A -OSPE: Configure the routers with the respective interface IP addresses Note that mask that is used is 255.255.255.0 so the wildcard mask … RouterB(config-router)# redistribute ospf 20. Notice the “redistribute eigrp 1 subnets” command on R3’s configuration. # View the OSPF routing table of the Huawei switch. The hello timer on R2 expires every … # Configure basic OSPF functions. This is usually required by the routing protocol as OSPF and EIGRP. Network X.X.X.X X.X.X.X area 0 #where the Xs represent the P2P network and wildcard mask between your MX and L3 This tutorial explains how to configure OSPF Routing protocol step by step with practical example in packet tracer. By default, when source protocols, such as, OSPF, RIP, and IS-IS , are redistributed into EIGRP , they are given an administrative distance of 170 and a seed metric of infinity . 4.EIGRP supports IPX and AppleTalk while OSPF not. Just a basic query, which i would like to get it clarified. RIP is a distance vector protocol. Output at router B . IGRP is a distance vector protocol. Summary routes can be created at both levels of the network: At routers R21, R22 and R23 to summarize their respective sites into the DMVPN cloud. Advertise their connected routes. Solved Objective Questions and Answers for EIGRP and OSPF 1. It still utilizes the same metric, which is “cost”. The default value is 110. Sounds like you might need to do a bit more reading. Even though the router "runs" the routing protocol ie. EIGRP or OSPF, when you configure the routing, you are actually configuring an interface of the router for the routing protocol. You will also change the metric type for EIGRP routes redistributed into OSPF. R2 (config)#interface se0/0/0. router ospf 100 log-adjacency-changes redistribute eigrp 100 subnets network 192.168.231.0 0.0.0.255 area 0. Today I was working through the standard OSPF walk through with Khawar’s class and we went to start configuring OSPF Authentication. command, and make sure that you have routes from OSPF populating the R2 routing table using the . Step 2. R2 (config-router)# redistribute ospf 1 metric 10000 100 255 1 1500. VPN (virtual private network) is a tunneling protocol used to set up a dedicated, encrypted connection or "tunnel" between two sites or between a site and a client. Figure 2 - Creating a EIGRP router instance. The tutorial below will focus on Routing Redistribution between OSPF and EIGRP and vice-versa. EIGRP is an advanced routing protocol that relies on features commonly associated with link-state protocols. Configuration part of OSPF includes process ID, Area ID and wildcard mask which make its setup a litter bit harder.
