EIGRP Evaluation Sim
You have been asked to evaluate how EIGRP is functioning in a network.
The configuration of R1 to R6 are posted below for your reference, useless lines are omitted:

Note: This sim uses IOS version 15 so “no auto-summary” is the default setting of EIGRP. You don’t have to type it.
You can download this sim to practice at http://www.digitaltut.com/download/ROUTE_EIGRP.zip. Please use GNS3 with version older than v1.0 to open it (v0.8.3.1 for example). IOS used in this lab: c3640-jk9s-mz.124-16.bin
Question 1
Explanation
First we need to get the IP address of R6’s loopback address by “show ip interface brief” command on R6:
Now we learned the R6’s loopback address is 150.1.6.6. To see the ratio of traffic that is load shared between paths, use the “show ip route 150.1.6.6” command on R1:
This means that after 19 packets are sent to 192.168.13.3, R1 will send 80 packets to 192.168.12.2 (ratio 19:80). This is unequal cost path Load balancing (configured with “variance” command).
Question 2
Explanation
Use the “show running-config” on R6 we will see a distribute-list applying under EIGRP:
With this distribute-list, only networks 192.168.46.0; 192.168.56.0 and 150.1.6.6 are advertised out by R6.
Question 3
Explanation
Check on both R2 and R4:
To successfully authenticate between two EIGRP neighbors, the key number and key-string must match. The key chain name is only for local use. In this case we have key number “1” and key-string “CISCO” and they match so EIGRP neighbor relationship is formed.
Question 4
Explanation
To check the advertised distance for a prefix we cannot use the “show ip route” command because it only shows the metric (also known as Feasible Distance). Therefore we have to use the “show ip eigrp topology” command:
Update: Although the “show ip eigrp topology” does not work in the exam but the “show ip eigrp 1 topology” does work so please use this command instead and we will find out the advertised distance on R1.
There are two parameters in the brackets of 192.168.46.0/24 prefix: (1810944/333056). The first one “1810944” is the Feasible Distance (FD) and the second “333056” is the Advertised Distance (AD) of that route -> A is correct.
Just for your reference, this is the output of the “show ip route” command on R1:
In the first line:
D 192.168.46.0/24 [90/ 1810944] via 192.168.12.2, 00:10:01, Ethernet0/0 |
The first parameter “90” is the EIGRP Administrative Distance. The second parameter “1810944” is the metric of the route 192.168.46.0/24. R1 will use this metric to advertise this route to other routers but the question asks about “the advertised distance for the 192.168.46.0 network on R1” so we cannot use this command to find out the answer.
Question 5
Explanation
Check with the “show running-config” command on R1:
In the “ip bandwitdh-percent eigrp 1 20” command, “1” is the EIGRP AS number while “20” is the percent of interface’s bandwidth that EIGRP is allowed to use.
Note: By default, EIGRP uses up to 50% of the interface bandwidth. The bandwidth-percent value can be configured greater than 100%. It is useful when we set interface bandwidth lower than the real capacity of the link (for policy reasons, for example).
need latest dumps. please send if you have to {email not allowed}
hello guys, I need ccnp latest dump. Please send if you have to wcgamer @ inbox dot ru
hi gyus i need latest dumps of route 300-115
Hi all, pass today with 802 score.
Got this EIGRP Evaluation Sim along with the OSPF Sim and IPv6 OSPF Virtual Link Sim.
– EIGRP Evaluation Sim was exactly the same, just had to use “show ip eigrp 1 topology” command (show ip eigrp topology didn’t work).
– OSPF Sim also the same, only with different names and IP addresses (copy running-config startup-config works).
– IPv6 OSPF Virtual Link Sim the same (copy running-config startup-config doesn’t work but it’s ok).
The rest of the questions almost all from this site.
I had premium member account.
Good luck ppl.

I just passed the Test
I got
EIGRP Evaluation Sim .. exactly the same
OSPF SiM .. OSPF process and area were different nothing more
IPV6 OSPF virtual Link Sim
passed score 802 .. minimum 790
most of the questions are found here
What is the answer for Question 2. Planning on taking the exam next week. is it Distribute-list using an ACL?
Hiii , is there any one pass the eaxm please??
A colleague of mine passed the exam last week, I will take it in 2 days.
