So here is something that can very well take some time to come around the corner, but be here just like that and impact all of us. The new Cisco IOS (15.0) licensing methods are potentially putting our educational ability to study using GNS3/Dynamips at risk of coming to an end.

Here is a read from an article published by Dan Hughes on etherealmind.com

However this week marked the beginning of the end for this old friend, with the announcement of the supported hardware platforms for IOS 15.1, we see that only ISR and ISR2 routers are supported. For architectural reasons, it’s never been possible to emulate these platforms in dynamips, so we’ve reached a place where new IOS software won’t be usable in dynamips. We can run 12.4 on the existing range of platforms, and 15.0 on the 7200 platform, and thats it.

Today, it doesn’t really affect anything, unless you want to try the new hold music feature in 15.1, but over the months, as we head into 15.2 and 15.3, then the software we can run in dynamips will become too old to matter any more. Exam blueprints will move on, features we want to use will only exist in the new versions, we’ll update our production and test networks, and slowly, dynamips will become a thing of the past.

For those of us who have invested heavily in our own training and lab equipment, it won’t make a huge difference. Adding a few second hand 1841′s won’t cost a fortune, although will use a lot more power and cooling than the single dynamips box does. But for the ordinary CCNA and CCNP student, it’ll be too much to buy, too much room taken up, and too much power and noise. They can use remote labs, but they really don’t give the flexibility of your own kit.

So Greg Ferro put up a petetion off of an idea Wendel Odom came up with regarding an educational copy of IOS.

Do us all a favor and lets give it a shot and support and sign this electronic petition!

Hello All! Hope your weekend and holiday has been a great one!

Here is another one of the final Cisco Network Academy labs. This one involves BGP and EIGRP. A lot of good tasks in this case scenario. I wish that they would have had many more lab scenarios since they are exactly whats on the lab. There definitely needs to be a new lab book developed - Maybe I’ll create one? Kidding!

Anyway … Onto the lab!

This is a lab from the Cisco Networking Academy Lab Portfolio.

I perform all of these labs on my own using my own knowledge and experience (warning and disclaimer). They may very well be implemented differently than a method you might choose. So long as it meets the requirements and works, essentially it’s acceptable (In my feeble opinion). But if you notice a terribly or complicated method used by me to achieve the goals and you feel yours is much easier, makes sense or is the standard; please do share - I’m always open to learning

P.S. If you would like to donate for the time it takes to do all of this, feel free to use the link below. Thank you in advance for any contribution you make

So here is another lab I put together based on some studies and reading recently. I basically put together the scenario, so if it’s lacking conveying the scenario in a professional manner, I apologize

This is basically a simple route redistribution and route manipulation lab. Simple, but requires a few steps that will test your ability to adapt to an already deployed network while implementing a new routing protocol.

Hope you enjoy!

Scenario

Company Tapan wants to enable EIGRP AS 1 on R1, R2 and R3. They would like to connectivity between all routers and subnets with the exception of the loopback interface on R1. R3 should NOT be able to communicate with R1’s Loopback interface. Unfortunately Tapan cannot eliminate advertisement of R1’s Loopback interface due to other network dependecies on the other side of R1 (unseen here).

Additionally Tapan is planning to segment the networks between R1, R2 and R3 using OSPF. They would like 2 OSPF areas. The OSPF area between R1 and R2 will be the core (Area 0). The area between R2 and R3 will be Area 1.

Tapan has determined that they’d like to reach R1’s loopback via OPSF. Tapan would like that R1’s Loopback interface be reachable via OSPF ONLY.

Tapan has hired you as the network consultant to configure their required network scenario.

When R3 can communicate with R1’s Loopback using the scenario above, your job is done.

Because R1 is a bit inflexible, the IP and EIGRP configuration is already in place and CANNOT be changed. Only OSPF can be configured on R1 to R2.

Ok - So if you’re not up yet on the Packet Pushers, you’re totally missing out on some good network discussion (usually) hosted by @Etherealmind, @ECBanks & @Danhughes1234ie. The greatness about this podcast is it’s like sitting around and chatting it up with guys in your office or at a tech conference or on a project with other project team members - Thats how I see it at least

There is no other agenda to these podcasts except talking about the topics. There is no vendor target, no advertisements, no bias - though we are all Cisco minded They cover subjects such as DDoS, IOS Licensing concerns, Dynamips, MPLS basics, Technical interview tips, datacenter switching and the list goes on!

Overall it’s a great show to listen to and best of all, you may know all the guests on the show from Twitter. So it feels even more realistic since you may have tweeted with these folks for some time now.

I enjoy the show very much and I enjoy the guests even more! I recommend you check out the Packet Pushers Podcasts! Trust me, you will love it!

Cheers guys!

Scenario

The International Travel Agency needs its core network set up for OSPF with
the specifications indicated in the diagram and shown below.

• Use the addressing scheme shown in the diagram.
• Use OSPF with various networks shown in the diagram.
• Configure the OSPF backbone area to be on Loopback0 on Headquarters.
• Configure the Frame Relay subnets as point-to-point subinterfaces. The link between Headquarters and East should be in area 100, and the link between headquarters and West should be in area 300.
• Area 300 should be configured as an NSSA.
• Configure East’s loopback interfaces to be in area 200. Summarize this area with the most efficient summary.
• Redistribute the loopback network on West into OSPF.
• Create virtual links as necessary for full connectivity.
• Make sure that all loopback interfaces get advertised with the correct subnet mask.

Yesterday the GNS3 team released the latest version of GNS3 in which a virtual host was introduced among plenty of other new features and fixes.

The most anticipated addition is the virtual host capability. I’ve had the chance to debug this myself and I must say it works great! I’m kind of use to vpcs, but if you havent figured that out and would like to simulate hosts in GNS3, just download the new version and have fun!

Onto the release post..

Submitted by admin on Wed, 06/16/2010 - 01:01

GNS3 0.7.2 is released. Here is a list of the changes in this version:

* Lot of small fixes (relative paths, link removal, .net loading, Ethernet switch connection to a Cloud etc.)
* Qemuwrapper: random MAC address for devices
* NPE-G2 option for c7200 routers (need a specific and uncompressed IOS image and C7200-IO-2FE, C7200-IO-GE-E, PA-2FE-TX and PA-GE are unlikely to work)
* Simulated switches: daisy chaining support
* Improved directory selection for new projects
* New translations: Bulgarian, Italian and Ukrainian
* Frame Relay capture option for all serial links
* Dialog to display an Ethernet switch MAC address table

The following features will work only with a Dynamips version > 0.2.8 RC2 which has not been released yet:

* OIR (Online Insertion and Removal) for c3660 and c3745 (only NM-4T).
* JIT sharing support (saves memory).
* C7200-JC-PA Jacket Card support. Allow the use of a slot 7 for c7200 routers with NPE-G2.
* QinQ support for simulated Ethernet switches.
* Interfaces statistics (Packets in, Packets out, Bytes in, Bytes out). Displayed in node tooltips.

Also, we provide a small Qemu image of Microcore Linux 2.10, ready to be used in GNS3 and which includes ssh, iptables, iproute, tcpdump and IPv6 support. A small integrated simple host that supports pings is planified for the next release as well as some surprises

Not every translations have been updated so far but we will release a separate package containing the translation when there are up-to-date.

Thanks to all our translators, beta-testers, moderators and users which make GNS3 beter after each version.

Enjoy!

Alright - Moving on and getting into some lab scenarios. No need to explain too much, all the information is below.

This is a lab from the Cisco Networking Academy Lab Portfolio.

CCNP Building Scalable Internetworks (BSCI 642-901) Lab Portfolio (Cisco Networking Academy)

Instructions
Plan, design, and implement the complex International Travel Agency (ITA)
EIGRP network based on the above diagram and following specifications.
Implement the design on the lab set of routers. Verify that all configurations are
operational and functioning according to the guidelines.

Scenario

The ITA needs its core network set up with EIGRP with the following specifications. It has also recently acquired Local Travel Agency, which was running OSPF. Use the addressing scheme shown in the diagram.

• The ITA core network is running EIGRP in AS 1.
• Summarize the loopback interfaces on R2 with the best possible summary to the other EIGRP routers
• Loopback 192 on R3 represents a connection to the Internet. Originate a default route into EIGRP from R3.
• The Local Travel Agency router, R4, needs to communicate with the ITA core via OSPF area 0.
• Redistribute OSPF into EIGRP.
• Originate a default route into the OSPF process from R3.
• Configure R2 to act as a DHCP server on the Ethernet subnet between R2 and R3.

Hope you are all doing well and celebrating the achievement of your CCNP or preparing to sit the exam very soon! Good luck.

Here goes the last of this BGP lab series - Next up? We’ll see! This lab will teach you how to configure a Route Reflector in BGP, you’ll learn how this type of configuration helps get around the BGP Split-Horizon rules where an iBGP peer cannot advertise a route learned from another iBGP peer to another iBGP peer .. Say that 3 times!

This lab also covers BGP filtering by using Prefix-Lists and aggregating addresses AKA BGP Summarization.

Keeping it going with BGP here! This is basically lab 3 from the lab portfolio. This one adds some EIGRP into the mix to help demonstrate how to get IGP routes into the routing tables and how that affects the overall routing including BGP.

This lab includes working with IBGP EBGP, the local preference and the Multi-Exit Discriminator

Lab Objectives: In this lab, you will configure both IBGP and EBGP. For IBGP peers in this lab to correctly exchange routing information, the next-hop-self command must be used along with the Local-Preference and MED attributes. This is to insure that
the flat-rate, unlimited-use T1 link is used for sending and receiving data to and from the AS 200 on ISP. The metered T1 should only be used in the event that the primary T1 link has failed. Traffic sent across the metered T1 link offers the same bandwidth of the primary link but at a huge expense. Ensure that this link is not used unnecessarily.

Jeremy and the GNS3 team has done it again - They’ve come about with a minor release to address some 0.7 bugs and set the ground for some future GNS3 stuff.. See the official release info below..

GNS3 0.7.1 is out, this is a minor version which corrects some bugs and improves some features. Here is a non exhaustive list:

• Qemuwrapper (option to listen on a IP/host and port).
• Basic support for external hypervisors.
• Some improvement for projects under GNS3 (still work to do).
• Many small bugs fixes (graphical, cloud connection etc.)

We still have a major bug to run multiple Qemu instance of a same virtual host on Windows (please this the following post for more details: http://www.gns3.net/phpBB/topic1914.html)

Translations and documentations will be updated for the next major release.

Greetings! Hope everyone is wrapping up their CCNP certifications before the July 31st deadlines. If you are still confused about what certs are valid after the deadline and want to know which you should be taking, have a look over here at my attempt to explaining it all.

I’ve been busy trying to absorb all of this study lately and well, It’e been tough! Whats the deal with life? Doesnt it know we want to become certified? So why must it get in the way?

I recently had surgery, the Wife became ill for almost 3 weeks (a very scary situation) and now work is ramping up as will :sigh: it seems almost impossible! Either way, all is well now. I’m back to good health and so is the Wife! Yay!

Ok - this is a simple lab of many that I have that I just need to package and put up. Sorry for the long gaps in between postings - I expect to do a better job once I complete this BSCI exam. I also plan to do a better job at posting lab challenges and scenarios where possible. The biggest problem is I’m still not at a skilled level yet to create any “tough” lab challenges. The best I can do is post what I find and use on my own for studying. I’ve got a lot of labs to post, just be patient with me.

Onto the lab! This is a lab from the Cisco Networking Academy Lab Portforlio.

Great source of LOTS and LOTS of labs. The bigger problem is the errors in the material - it can make you crazy. None the less, go through them; try your best and indulge is getting use to the commands more importantly. If you’re at the level where you can detect and mitigate the errors, good for you and please do share. If not - Just focus on the commands. The best way I can recommend coping with the errors, but still making use of it all.

Ok - So here is another CCNP BSCI / CCNA lab challenge. This lab is part of Chris Bryant’s CCNP lab manual.

This is my second visit to these labs after completing the reading material and not having to look at a single bit of the guide for help to config this up! Impressive to me, but I do realize these labs are quite simple. Nevertheless; they are labs I had no knowledge on how to config 5 months ago (to this extent) so I’m happy

No lab is too simple in my opinion - any labbing is good labbing! As I understand it knowledge in labs like these are sufficient enough. I enjoy labs that aren’t overly complicated, while allowing you to get comfortable with commands and such. Take advantage now, cause the CCIE level labs are not as nice! With that said, master these labs and you should be able to pass the CCNP BSCI/ROUTE exams, or at least we hope

So if you didn’t check out the first part of this lab, you can find it here. That lab will allow you to configure the core part of this lab from step 1. The configs included in the archive here are the initial configs already applied to the routers. There is a text file that contains the lab objectives similar to below, as well as the solutions to this lab.

Try not to cheat! Don’t look at the solutions file until you absolutely need to.. If you’ve broken your keyboard, monitor and cursed out a router and protocol that wont answer you - I forgive you, go ahead and peak at the solutions file

Onto the lab!

-From R4 ping the loopback interfaces of R1, R2 and R3
-Configure Area 34 as a total stub area
-Observe the routing table of R4

5
-Reconfigure Area 34 as a normal area - No stub or total stub configurations
-Remove any redistribution configuration on R1
-Reconfigure loopback 12 with IP 12.12.12.12/8 on R1
-Reconfigure loopback 13 with IP 13.13.13.13/8 on R1
-Reconfigure loopback 14 with IP 14.14.14.14/8 on R1
-Reconfigure loopback 15 with IP 15.15.15.15/8 on R1
-Place loopbacks 12, 13, 14 and 15 into OSPF Area 1
-Observe the routing table of R2 - particularly the loopbacks on R1
-Configure area range commmand on R1 to summarize the new loopback routes - Which command do you use? Summary-address OR area-range?
-Observe the routing table of R2 - particularly the summarized routes for the loopbacks on R1
-Ping 12.12.12.12 from R2 - Success?

6
-Create loopback 16 with IP 16.16.16.16/8
-Create loopback 17 with IP 17.17.17.17/8
-Create loopback 18 with IP 18.18.18.18/8
-Create loopback 19 with IP 19.19.19.19/8
-Redistribute the new loopbacks into OSPF as E2 routes - we dont want classful routes
-Observe the routing table of R2 - particularly the new loopbacks of R1
-Summarize the networks you just redistributed into OSPF - Which command do you use? Summary-address OR area-range?
-Observe the routing table of R2 - particularly the summary route for the (16-19) loopbacks on R1

IPExpert took the time to put together a pretty good tutorial ranging from explaining what GNS3 is, to loading IPExpert labs and installing GNS3 & PuttyCM on Windows 7. They also go through some definitions to some of the settings that many may not know about.

They do mention that Windows is not the optimal choice OS for GNS3. x64 versions of linux, like Ubuntu are better choices for your GNS3 OS. Through testing and swapping between the two, I couldn’t agree more.

Something they point out right out of the box is what devices are supported.

Platforms and modules supported by GNS3

1. 1700 routers
2. 2600 routers
3. 3600 routers
4. 3700 routers
5. 7200VXR series
6. NM-16ESW switching module
7. WIC modules
8. NM-CID
9. NM-NAM
10. NM-xT/ NM-xFT
11. Native Etherswitch support and Frame-Relay support

They created the tutorial using GNS3 0.7RC1, which has been replaced by the official GNS3 0.7 STABLE release, but nothing changes in the scope of the IPE tutorial. Not sure IPE realized this? There are some huge performance and module changes/additions to the latest GNS3 release.

Eitherway, the IPE tutorial will definitely help someone looking to install the whole kitchen sink!

Internetwork Expert also has their own adaptation of GNS3 for their material as well. Less of a tutorial, but if you’re already up and running, just load their topologies and you should be ready to rock!

So as expected - we’re going to start seeing some folks rolling out labs that are based on the new CCNP track topologies. This new submission comes from Steve - He turned multiple CCNP ROUTE study exercises into a full EIGRP lab exercise as best as he can while covering almost everything possible in regards to EIGRP configuration. Definitely a FULL EIGRP lab giving some great practice to candidates of CCNA, CCNP and even CCIE

Thanks Steve..

Topology:
- 2 Core routers
- 2 Wan routers (Wan/core a linked through a switch)
- 3 Branch routers, each having a Frame-Relay PVC to each Wan Router.

All routers are 2691 used with IOS c2691-adventerprisek9-mz.124-5a.bin
(7x 192Mo)

EIGRP Topics covered:
- Basic EIGRP config
- Dynamic Neighborship
- Auto-summary issues
- Split-horizon
- Neighborship settings (hello-timer, hold-timer eigrip RID)
- Static neighborship
- EIGRP authentication
- Passive interface
- Interface bandwidth over frame-relay
- EIGRP bandwidth usage
- Stub routers
- Offset-list

Usage of that feature in the lab is not the best solution to solve the
issue i mentioned in the lab
but at least it’s an occasion to configure it, to analyze EIGRP RD/FD
and to see the effect of such settings.

- Variance
- Default-route/network
- EIGRP Summarization
- Route filtering (prefix-list / route-map)

You’ll find 2 archives .. one with basic config (hostname, interface
config etc), and the second with the full config of the lab.
Both contain the PNG file. Explanations can be fond in each lab and on
the PNG file too.
