EIGRP OSPF Redistribution Sim

May 8th, 2014 in Lab Sim, LabSim Go to comments



Answer and Explanation:

First we need to find out 5 parameters (Bandwidth, Delay, Reliability, Load, MTU) of the s0/0/0 interface (the interface of R2 connected to R4) for redistribution :

R2#show interface s0/0/0

Write down these 5 parameters, notice that we have to divide the Delay by 10 because the metric unit is in tens of microsecond. For example, we get Bandwidth=1544 Kbit, Delay=20000 us, Reliability=255, Load=1, MTU=1500 bytes then we would redistribute as follows:

R2#config terminal
R2(config)# router ospf 1
redistribute eigrp 100 metric-type 1 subnets
R2(config-router)#router eigrp 100
R2(config-router)#redistribute ospf 1 metric 1544 2000 255 1 1500

(Notice: In fact, these parameters are just used for reference and we can use other parameters with no problem. Also, a candidate said that the simulator didn’t accept the Bandwidth of 1544; in that case, we can use a lower value, like 128.

If the delay is 20000us then we need to divide it by 10, that is 20000 / 10 = 2000)

Note: “usec” here does not mean microsecond (which is 1/1000 milliseconds) but means millisecond. In short usec = msec. I don’t know why they use the word “usec” here but just think it is “msec” (According to this link: http://www.cisco.com/en/US/tech/tk365/technologies_white_paper09186a0080094cb7.shtml#eigrpmetrics: “The delay as shown in the show ip eigrp topology or show interface commands is in microseconds”)

For R3 we use the show interface fa0/0 to get 5 parameters too

R3#show interface fa0/0

For example we get Bandwidth=10000 Kbit, Delay=1000 us, Reliability=255, Load=1, MTU=1500 bytes

R3#config terminal
router ospf 1
redistribute eigrp 100 metric-type 1 subnets
router eigrp 100
redistribute ospf 1 metric 10000 100 255 1 1500

Finally you should try to “show ip route” to see the network (the network behind R4) in the routing table of R1 and make a ping from R1 to this network.

Note: If the link between R2 and R3 is FastEthernet link, we must put the command below under EIGRP process to make traffic from R1 to go through R3 (R1 -> R2 -> R3 -> R4), which is better than R1 -> R2 -> R4.

R2(config-router)# distance eigrp 90 105

This command sets the Administrative Distance of all EIGRP internal routes to 90 and all EIGRP external routes to 105, which is smaller than the Administrative Distance of OSPF (110) -> the link between R2 & R3 will be preferred to the serial link between R2 & R4.

A reader on our site has a closer explanation for the “distance eigrp 90 105” command so we quote it here for your reference:

The “distance” refers to the administrative distance of the routes provided by a given routing process. By default, internal (which means non-redistributed) EIGRP routes are given an administrative distance of 90 while external (redistributed from another routing process) EIGRP routes are given an administrative distance of 170. The default administrative distance of OSPF is 110. The administrative distance measures the “distance from the truth” and tells the router which routes are more trustworthy. Lower administrative distance = more trustworthy. For this reason, connected routes have an administrative distance of 0. They are the MOST TRUSTWORTHY, because they are physically connected to the router. When making a decision about which route to install in the routing table, the router looks at administrative distance first. The metric (or cost) is only considered if two routes have the same administrative distance.

In this case, R2 will learn about R4’s loopback network from both R4 and R3. The route from R4 will be in OSPF (admin distance of 110) because R2 is also running OSPF while the route from R3 will be an external EIGRP route (administrative distance of 170 by default). Since the OSPF route has a lower administrative distance, it will get placed in R2’s routing table and the R3-provided route will be ignored. This is not optimal, since the path through R3 is a faster, more reliable path. To fix this, we change the administrative distance of external EIGRP routes at R2 by using the “distance eigrp 90 105” command. This sets the administrative distance of internal EIGRP routes to the default of 90 and changes the administrative distance of external EIGRP routes to 105 (less than that of OSPF routes). Now, when R2 learns of the loopback network from R4 and R3, it will install the now lower administrative distance external EIGRP route from R3 and our traffic from R1 will take the faster path.

Note: Please check the OSPF process numbers first before typing these commands.

If you want to have a closer look at this sim and understand more about the “distance eigrp” command, please read my OSPF EIGRP Redistribute Lab in GNS3.

    1. Dont believe the people said 149q is invalid…it’s valid but there is about 10 to 15 new questions not in 149q dump that you can find it in 183q dump.
    2. Another dump you need to read carefully is in this url :

    I had the lab with Fastethernet link, but I was not able to use distance command “distance eigrp 90 105”.

    When tried using question mark “distance eigrp 90 ?” it showed no avaiable options or description. I submitted the full command, it was visible in running config but no change in ip routing table happened. Traceroute was still the same via serial link. Finally I removed the command and go to next question.

    Most quesions are still valid. Maybe had some new ones. CHAP drag&drop .
    Pased with 790 points . Dont forgot to read the book and good luck .

    i downloaded the lab from tut and ran in my gns3. It looks like the answer does not correspond to the lab because IEGRP is already redistributed into OSPF. We need to do redistribution the other way. From OSPF into EIGRP. Anyone noticed that the answer is wrong ?
    I might miss the explanation in the thread but really don’t want to read 30 pages of posts.

    Can you guys check the lab?

  47. AFI
    January 9th, 2017

    @ ADMIN – whoever that is.
    I dont think OSPF EIGRP redistribution lab is complete. i think there needs to be a default route in R1 for it to ping R4 loopback address.

    i just ran files, i had to redistribute in R2 & R3. only issue I found is mentioned above.

  48. malik

    In this Redistribution lab, There is no need to use match and set tag values for redistribution EIGRP to OSPF and OSPF to EIGRP?

    Refer to the following configuration command.
    router(config)# ip nat inside source static tcp 8080 80
    Which statement about the command is true?

    A. Any packet that is received in the inside interface with a source IP port address of is translated to
    B. Any packet that is received in the inside interface with a source IP port address of is translated to
    C. The router accepts only a TCP connection from port 8080 and port 80 on IP address
    D. Any packet that is received in the inside interface with a source IP address of
    is redirected to port 8080 or port 80.

    here in tagwa dump it say the correct answer is a but i think it b , can any one advice

    I think this command parameters is not correct:
    R3(config-router)#redistribute ospf 1 metric 10000 100 255 1 1500

    because fast ethernet BW is 100,000 and its bandwidth is 100 witch become 10 after divided it by 10
    on other-hand I don’t think its right to change AD of EIGRP where this case a loop issue
    the rule is to make sure that AD of internal Routing AD of external EIGRP (105)

  62. Malak
    January 17th, 2017

    the rule is to make sure that AD of internal Routing less than external Routing…
    AD of internal OSPF (110) bigger than AD of external EIGRP (105), this may cause a loop
