Develop an study case from the ground up
Plan and implement a network design and configure each device from the begining :
begin with one main office and, as if was not planned add 1-2 branch offices, solving the challenges (and reconfiguring the devices as).
Begin with a not too much complex case: 2 switches (3-4 departments) and 1 router with internet access, then adding another switch, another department, make vlan, secure port, secure access, and then adding another internet connection, then adding a new little branch office and perhaps a second one with different protocol ) . Because it perhaps will get to big, perhaps will be nice to begin with a base scenario and make some child scenarios …
Data Center/Branch Network
I would like to ask if you can make a scenario where you emulate a HQ data center which consists of a WAN Router which is connected to MPLS with ebpg between the CPE and PER routers and then suggest if we should either do redistribution or ibgp/ospf/eigrp for our IGP protocol to have bidirectional connectivity. Also add a firewall/router which is connected to the internet and you have one or two branches connection back to it through a vpn/gre tunnel and best practices on how to configure these sites.
I would like to see more scenario which we see often in real world production environment. Thanks

Lesson on PPPoE and L2TP
Can you pls create a lesson on PPPoE and L2TP which describes in detail of both the protocols.
Cisco Group Encrypted Transport VPN (GET VPN) is a set of features that are necessary to secure IP multicast group traffic or unicast traffic over a private WAN that originates on or flows through a Cisco IOS device. GET VPN combines the keying protocol Group Domain of Interpretation (GDOI) with IP security (IPsec) encryption to provide users with an efficient method to secure IP multicast traffic or unicast traffic. GET VPN enables the router to apply encryption to nontunneled (that is, “native”) IP multicast and unicast packets and eliminates the requirement to configure tunnels to protect multicast and unicast traffic.
VIRL -labs-basic/intermediate configuration
I love VIRL but I am not that great with it. I am not that fond of their forums either. would be great to have some basic and intermediate labs setup in VIRL so that we can follow and use VIRL. not talking about installing VIRL and setting it up I am talking about using it for CCNA and CCNP and up.

Application access authentication using LDAP is widely used these day. A tutorial explaining basic LDAP/AD config and going through sample example like LDAP search etc will be really useful
CCDP & CCDE
Some think that the design aspect of networking and certifications aren’t as useful as others, and that it’s meaningless in the industry. I personally feel that it is in EVERY part of networking and is a key factor to an optimal network. Often we learn about different devices and get a brief high-level explanation of their position in the design of the network; however, when it comes to designing the Internet edge, the WAN edge, and other modules of the enterprise network, it is very important to know the details of what goes where and how it should be configured. That gives you the baseline; then depending on organizational needs and constraints, we work from the baseline with various options that can produce the desired results,
We find bits and pieces of information here and there, given whatever technology we’re studying; nowhere except for Cisco documentation, which in itself only gives you bits and pieces, is there any instruction or reference that is complete with detail about each module of network design.
I feel this would be very useful and give the world of network engineers a better picture. Understanding what a device does and how to configure it is great, but understanding the role and the key position of players in the game is important as well.
include IOS release info for each topic/output
i’ve noticed much of the RS output is from 12.x code, which is not completely accurate in 15.x code. I understand it adds time to your content development cycle but it is very helpful for students learning / validating their knowledge

Traffic monitoring on a cisco router
I am often turning up new sites and circuits on the job. The client traffic coming in to my edge router via a LAN interface and trying to connect to an application my company hosts at one of its 32 datacenters. I am familiar with commands on the router such as ip accounting or setting an acl to log but feel like I could use much more detail and maybe some more methods. In the real world it seems this arsenal of traffic monitoring skills (only using the router not other tools) is essential. Maybe you could provide some methods as to how you would interact with the customer when troubleshooting connectivity to hosted application across an MPLS cloud.

WAN Links overview
Hi Rene, I’m still fairly new at networking. Perhaps I’m getting ahead of myself but I think I’m missing some basic information about the various types of WAN links. I’ve configured serial links using WIC-1T’s and HWIC-1DSU-T1’s, what I don’t understand though is how these would be implemented in the real world. For example, what is the purpose of a WIC-1T when its cabling is restricted to such a short distance. Wouldn’t fastethernet be a better solution?
Network Engineering interview topics covered

I could much, if any BGP video lessons. Would it be possible to add some please?
Please create a chapter on the principles of multicasting with explanations on protocols like IGMP and PIM-SM and concepts of pruning etc…Some of the concepts are still abstract. Thxs
Please cover CCIE Written Emerging Technologies
Recently I started to work on the CCIE Written. There is a “Emerging Technologies” section that we cannot find good study materials. Please cover them. Thanks.
Network Management Software
It would be great if we could have a course for any Network Management software like Solarwinds or PRTG,
this is required for any Network job.
CCNA/CCNP RS labs, Security and CCNA cloud
We got many nice topics from you, though It would be great if you can add 1) CCNA/CCNP R&S practical labs, 2) CCNA Security full topic and 3) CCNA cloud topic. Thank you.
Edge Network Setup With Redundancy For SMB
Please create a course with full redundancy at the Distribution/Collapse Core for a small business Setup. with dual connections to the Internet either using routers at the edge or ASA firewalls (also explaining whats the difference or when to use either or). I also would like to know why there has to be a Switch in between the Edge Router and the Firewall or Switch at the Edge. it seems that security auditors like to see a switch in there.
Cisco Cyber Ops (CCNA)
Would be awesome to see a course regarding the Cisco Cyber Ops (CCNA) 210-250 & 210-255 since it is a fresh yet very promising direction to develop in and no normal courses available yet anywhere!
OSPF Summarization and Default-Information Originate in OSPF Network that use more than one ABR
I would like to know how to prevent asymmetric routes when we use summarization in more than one ABR and defaul-information originate.
For example, 3 ABRs connect the backbone area (0) to area 1.
As ABR announces the lowest cost summarization of one of its interfaces, we will end up having asymmetric routes.
More videos Required and also seperate video section recommended
Please try to include more video classes. your explanation method is simple and easy to follow. so more videos will be effective.
kindly consider separate video section (including which attached to topics) in this website
can we have Nexus VPC configuration and troubleshooting?
IPv6 DHCP relay
Please could you include IPv6 DHCP relay within the IPv6 DHCP section, this is setup slightly differently to IPv4 DHCP relay so would be useful to know.
Hello，I’am a Chinese student, my English is bad. I cannot understand your Video content without subtitle…. I beg you to add subtitle（Chinese means 字幕）in your QoS Video.please please please…..
Redistributution between OSPF and EIGRP
It is likely that the CCNP route exam has questions regarding redistribution between OSPF and EIGRP. It would be helpful if you could cover this in more detail.
MLDP based MVPN
Widely used n the SP..you can add this to your MPLS list
eBGP with ipv6 examples
Example under eBGP section with ipv6 addresses just like those of ipv4 and explanation of dual stacking along with example.
Overlay transport virtualization. OTV
Can you please provide an example using OTV when you want to extend current VLAN to a DR site?
Require Lab workbooks
It would be great if you add lab workbooks and or some real topology .
The small piece of topology does not help much in real life ,
It’s ok for understanding the concepts
Please create a lesson on EIGRP OTP – it’s on the CCIE blueprint but seems to often be ignored!
Considering that the CCIE R&S is great when I will finish would be fantastic having another CCIE done on the same way. Security would be brilliant!
it would be great if you could get a lesson on igmp proxy (ccie l2 technology)

Do this if you are not an employee of CISCO
A walk-through of BGP Add-Path would be great, thanks.
Could you make some lessons abut Traffic Engineering?
Looking for practical topics in SP domain
Would need details on
eBGP NNI OPTIONS ( A/B/C)
Please cover 6PE/6VPE, it’s on the CCIE syllabus!
CISCO IWAN Solution
IWAN solution now take into consideration for many enterprises like banks and SDN our simply explain for every topic will be very useful for such complex solutions
Are you ever going to offer Security Courses
Wireless and DC in depth.
You are awesome. I love your approach towards teaching R&S. Looking forward for more wireless technology and DC soon.
Full marks for R&S 🙂
Thanks and regards
We appreciate If you create some Lesson on VPLS/HVPLS and MPLS TE at your soonest.Thx
Could you modify the web page with a check-box next to each subject, which would assist in keeping track of what subjects have been read.
How to define routes in host devices like computers, servers especially when you have 2 different NICs connected to 2 different networks and you want to seggregate traffic from 2 set of networks.
Normally this is case when we use one interface for management and other for use traffic.
video not text
Create videos with text instead of text only specially for CCIE R&S
ospf global timer
ospf timers : lsa pacing, lsa throlling arrival time
A Day in the Life – Network Engineer
Sometimes during my preparation for exams, I wonder how often do I really get a chance to apply these commands and knowledge at work when I find a job as a Network Admin? How many times does a company need to change the routing protocol on their network? or how many times they need to create VLANS?
When a network is setup, it should be up a running …so what would be my job then as a network admin when there are no issues to fix in the company? Am I going to forget all these commands if I don’t’ use them much?
I really would love to see a course that will go through everyday work life of a Network Admin/Network Engineer so that I can relate more what I am learning to what I am practically going to use a real world.
UDP dominance TCP starvation
impossible to find resources that explain the underlying mechanism of this phenomenon !
Here is how it is defined :
TCP starvation/UDP dominance likely occurs if (TCP-based) Mission-Critical Data is assigned to the same service-provider class as (UDP-based) Streaming-Video and the class experiences sustained congestion. Even if WRED is enabled on the service-provider class, the same behavior would be observed because WRED (for the most part) manages congestion only on TCP-based flows.
Granted, it is not always possible to separate TCP-based flows from UDP-based flows, but it is beneficial to be aware of this behavior when making such application-mixing decisions within a single service-provider class.

Multicast over MPLS
You have already covered mulitcast in great detail and i must say it has cleared most of my doubts, could you please cover multicast over MPLS too since i dont find any good explanation over internet. I would really like to see your way of teaching on the said topic.
Thanks for considering my request.
