EIGRP CCNP 1

I somewhere solution for this lab?

Hey,

Great lab and most of the part where doable for me
But i have no clue how to do this:
Ensure only one path is used between router Walnut and Lyptus without breaking the EIGRP neighbor adjacency. You are not allowed to change the metrics.

any inputs?
Regards

Hello,
Change EIGRP maximum-paths to 1..

Hi Rene,
I am fond of this site, I have learnt many things from your Labs, i really appreciate your all Efforts.

Is there any possibility to get the Video or Final Configs or this Lab, Pls.

I will be great full to you.

Hello Aqeel,

I'm glad you like it here. This video is still on my to-do list, I'll see if i can do it this week.

Meanwhile you can drop your questions here and I'll help you OK?

Hey Rene I have a couple questions... Check my understanding on these few things.. Did I do them right?

"Make sure router Alder will use the serial 1/0 interface as the primary link."

I changed the delay on the fastethernet interface to accomplish this

"The summary route you just created should show up with an administrative distance of 51 on router Walnut."

I ran the command "#IP summary-route EIGRP 1 0.0.0.0 248.0.0.0 51" on walnuts fastethernet 3/0 and 2/0 interfaces

That's the correct command. It installed the route but I feel like I'm missing one step.

"Configure router Walnut so the loopback0 interface of router Lyptus will not be advertised towards router Cherry and Maple.
Ensure only one path is used between router Walnut and Lyptus without breaking the EIGRP neighbor adjacency. You are not allowed to change the metrics."

I used distribution lists to accomplish these two... Was that the best method??

Hello,

great lab! I haven't had the time to complete it yet, but I finished at the point were we set the AD of the summary route.

As Matthew stated, I was also curious about the fact that although I changed the AD on the summary and the summary did get installed in the routing table, the AD on the routing table of the neighbor router stayed the same. And then I remembered that Rene had a similar task in the CCNA topics, where he explained that the AD has only local significance, so if it is changed in a router, it won't get propagated to the neighbors.

Anyway, today I hope I finish the lab.

By the way, great work Rene! It motivates us to dive deeper into things and also see things that won't come easily around in our working environment!

Thank you for the effort!

Hello Matthew & Katerina,

Let me answer some of your questions:

EIGRP uses bandwidth and delay by default, optionally you can enable load and reliability. If you used delay to influence the metric you can make it use the serial link so this is perfectly fine!

This is how you configure a summary and also how you can change the administrative distance. For EIGRP you need to configure the summary on the interface level. Keep in mind that AD is always local.

Using the distribute list is a good idea. This will influence which prefixes you advertise/receive from/to neighbors without breaking the EIGRP neighbor adjacencies.

Your memory serves you well the AD is always local on a router.

Glad you enjoyed the lab!

• Router Walnut should send a summary route towards router Lyptus which only includes the loopback0 interfaces of router Alder, Cherry, Maple and Walnut. The summary route has to be as specific as possible.

I read in above post that the correct way to complete this is
--ip summary-address eigrp 1 0.0.0.0 248.0.0.0 51

I have two question regarding this. According to the step listed in lab the summary route should only include loopback address of first four routers. However the summary address listed in command above summarizes loopback addresses of all 7 routers. So is it correct?

Second how to check the AD on this summary route on router Walnut. Agreed that the AD set is locally significant. But what command output shows the that it is set as AD 51.

Am I missing something or is there a mistake in the diagram regarding Lyptus and Walnut.

Lyptus Walnut
Fa 0/0 54.5 Fa 3/0 54.4
Fa 1/0 45.5 Fa 2/0 45.4

I'm assuming one of WalnutsLyptus's subnets should be labeled 192.168.54.0/24 and this exercise doesn't use etherchannels.

@Sohaib Atta

These routers have the following networks configured on their loopback interfaces:

1.1.1.0 /24
2.2.2.0 /24
3.3.3.0 /24
4.4.4.0 /24

We need to summarize in the first octet and I need to summarize on a bit boundary, so what are my options?

0.0.0.0 /7 will cover 0.0.0.0 and 1.0.0.0.

0.0.0.0 /6 will cover 0.0.0.0, 1.0.0.0, 2.0.0.0 and 3.0.0.0 but i'll miss 4.0.0.0.

0.0.0.0 /5 will cover 0.0.0.0, 1.0.0.0, 2.0.0.0, 3.0.0.0, 4.0.0.0, 5.0.0.0, 6.0.0.0 and 7.0.0.0.

That's why we need the 0.0.0.0 /5. /5 in decimal will be 248.0.0.0.

You can find the AD in your routing table, just do a "show ip route" and it will show up behind the summary route.

@Dennis

You are right this is a typo. The configuration is correct however.

Hey guys this lab is not working for me.
I get error that nothing is connected to Port 7.

I have the correct IOS, is there anything else I need to change?

Do you have issues with any other topologies that you downloaded? Most of the problems are related to filenames/foldernames/IOS names and such.

Try the following article to see if it resolves your error:

http://gns3vault.com/Faq/203-bad-number-of-parameters-1-with-minmax22.html

"•Router Lyptus shouldn't receive any query packets for lost networks. Configure this but make sure not to break connectivity."
I need help with this bullet point.
How can this be achieved? Enabeling Lyptus as a stub area breaks the coonection.

thanks for your time, these labs are great!

Hi Rene.. Could you please upload the lab video ? thnx

Ensure router Alder does not send EIGRP packets towards its loopback0 interface.
i made loopback 0 passive interface..is that the correct way?

- Configure router Walnut so the loopback0 interface of router Lyptus will not be advertised towards router Cherry and Maple.????????? Help me plz..

Configure router Walnut so the loopback0 interface of router Lyptus will not be advertised towards router Cherry and Maple.

I tried by rout-map and PBR...but I lost EIGRP routing table on Lyptus...what is the solution?PLZ tell me..

Thank u about this Lab....Strong effort...I love it

nsure only one path is used between router Walnut and Lyptus without breaking the EIGRP neighbor adjacency. You are not allowed to change the metrics.

I used access list and rout-map the Ip policy on fa0/0 and fa1/0

Could you add the solution of this lab?

Using an access-list and PBR could be one way of dealing with this issue. I'll record the video this week and upload it...that'll answer all your questions

enter your message here...

On Walnut:
Create a route map that sets the next-hop Ip address to one of the fastethernet links on Lyptus.

Create an access -list to match all traffic and add a permit statement to your route map referencing this access-list

Apply the route map to the interfaces on Walnut that connect to cherry and maple:

i.e:

ip access-list extended TEST
permit ip any any

route-map TEST permit 10
match ip address TEST
set ip next-hop 192.168.45.5

interface FastEthernet0/0
ip address 192.168.24.4 255.255.255.0
ip policy route-map TEST

Thinks this is a correct way of doing this but rene will put us right!

Yes I did this to use one path and was good...

This is a good method of doing it. I hope to do some video recording this + next week, i'll do this one for sure so you can see my solution.

Hi all,
New guy on deck here. What do I need in order to participate and view the labs?

Hi,

Just register, login and you can get started. At the bottom of each lab you'll find the attachments with the GNS3 startup configuration files.

Most of the labs have the final config + video solution as well.

Rene

Help me

I don´t have idea how to do this.

•Router Lyptus shouldn't receive any query packets for lost networks. Configure this but make sure not to break connectivity.

thanks

Hi Guys,

I share my configs final about this lab.
