EIGRP GRE Troubleshooting Sim

March 19th, 2018 Go to comments

Refer to the topology below. Your company asks you to identify the issues in Phase 1 EIGRP implementation. You have console access on R1, R2, R3 Branch1 and Branch2 routers. Only use show commands to troubleshoot the issues.

Question 1

Explanation

R1 routing table does not have any EIGRP learned routes so R1 or the link between R1 & R2 is the most likely problem. We should check if the IP addresses on R1 and R2 are correct or not with the “show ip interface brief” command.

R1_show_ip_interface_brief.jpg

Note: You should check the IP address of R2 E0/0 interface (the interface connected to R1) as well.

Question 2

Explanation

The “main office” here refers to R2 (and other routers behind it). Check Branch2 with the “show ip route” command:

Branch2_show_ip_route.jpg

We can see Branch2 only uses 192.168.12.1 (Branch 1 – the secondary path) to reach R2 and the subnets behind. Branch2 does not use the primary path (directly connected to R2) so there must be a problem with the connection between R2 and Branch2. Check Branch2 router with the “show running-config” command and we can see an access-list is blocking EIGRP packets advertised to Branch2.

Question 3

Explanation

This issue is same as Question 2 but this time it is R3 which causes the issue. We can check R3 with the “show running-config” command.

R3_show_run.jpg

Question 4

Explanation

In this question we should check the local routers to see if these subnets have been advertised or not as there are many issues in the path which prevent these subnets from being shown in the routing tables.

When checking Branch1 router, we notice “network 172.16.0.0” is missing under EIGRP 200 so answer D is correct.

    hi ethan can you provide the questions you got for this this lab and what were the answers, are these mcq questions or do you have to configure the router

    9.tut please provide the question of this sim???????????

  13. ethan
    March 20th, 2018

    The questions is quite familiar with the previous GRE tunnel questions. It is just that they have modify the configurations to create new problem scenario. For example , supposed there is answer saying the router is configured in different AS for the previous SIM lab. The new one they make the router to be in same AS number and they removed the router network from the EIGRP . So instead of answering the question with ” the router is configure to be on different AS” the answer would be the network statement is missing from the EIRGP network.

    to 9tut.. the int 0/0 is connected to ISP router, u should, say check int 0/1 of R1, or 0/0 of R2. R1 0/1 ip address is 192.168.14.5 and R2 Int 0/0 is 192.168.14.2. i think this Q need for more clarify.

    Just passed today with 950 points. I warn you if you dont have good fundation you will fail. I had 6 simulations and they were all tricky. Keep practising with routing. Many questions from here still.

    Question 1
    Examine the R1 routing table. None of the internal routes other than locally connected appear in the routing table.
    Which cause of the issue is true?
    D. IP address was misconfigured between the R1 and R2 interface

    Question 2
    The traffic from Branch2 to the main office is using the secondary path instead of the primary path connected to R2.
    Which cause of the issue is true?
    C. EIGRP packets were blocked by the inbound ACL on Branch2

    Question 3
    The GRE tunnel between R3 and Branch1 is down.
    Which cause of the issue is true?
    C. The EIGRP neighbor relationship was not formed due to EIGRP packets blocked by inbound ACL on R3

    Question 4
    You are verifying the EIGRP configurations in the topology.
    Which statement is true
    D. Branch1 LAN network 172.16.12.0/24 is not advertised into the EIGRP network

    A. EIGRP neighbor relationship was not formed due to AS mismatch between routers R1 and R2 B. EIGRP neighbor relationship was not formed due to K values mismatch between routers R1 and
    R2 C. EIGRP packets were blocked by the inbound ACL on R1 D. IP address was misconfigured between the R1 and R2 interface
    Answer: D
    Question 2
    The traffic from Branch2 to the main office is using the secondary path instead of the primary path connected to R2. Which cause of the issue is true?
    A. The network 192.168.11.0/30 was not advertised into EIGRP on Branch2 B. The IP address was misconfigured between the Branch2 and R2 interfaces C. EIGRP packets were blocked by the inbound ACL on Branch2 D. The primary path has more link delay configured than secondary path which causes EIGRP to choose the secondary path
    Answer: C
    Question 3
    The GRE tunnel between R3 and Branch1 is down. Which cause of the issue is true?
    A. The tunnel source loopback0 interface is not advertised into EIGRP in Branch1 B. The tunnel source loopback0 interface is not advertised into EIGRP in R3 C. The EIGRP neighbor relationship was not formed due to EIGRP packets blocked by inbound ACL on R3 D. The EIGRP neighbor relationship was not formed due to the IP address being misconfigured between the R2 and R3 interfaces.
    Answer: C
    Question 4
    You are verifying the EIGRP configurations in the topology. Which statement is true?
    A. Branch2 LAN network 172.16.11.0/24 is not advertised into the EIGRP network B. Branch2 LAN network 172.16.10.0/24 is not advertised into the EIGRP network C. R3 server farm2 network 10.20.30.0/24 is not advertised into the EIGRP network D. Branch1 LAN network 172.16.12.0/24 is not advertised into the EIGRP network
    Answer: D
