Create a course with NX-OS Topics.
It would be great if we could get some basic to more advance troubleshooting across the core technologies EIGRP/OSPF/BGP/MPLS/Multicast. That really reinforces the foundation that I am learning and get a deeper understanding of these technologies.
A lot of your topics show you capturing traffic via Wireshark. Create a topic(s) exclusively on how to effectively use Wireshark.
A Lab after every major topic
A Lab sample or simulation would be great after every major topic. Currently im studying CCNP Route, For example on EIGRP, it covers:
-Introduction to EIGRP
-Basic EIGRP configuration
-EIGRP Neighbor Adjacency
-EIGRP Neighbor and Topology Table
-EIGRP Unequal Load Balancing
-How to Configure EIGRP Unequal Load Balancing
-EIGRP K Values
-EIGRP Hold Time and Hello Packets
-EIGRP Stuck in Active
-EIGRP Default Network Route
-EIGRP Filtering with distribute-list
-EIGRP Filtering with prefix-list
-EIGRP Route-map filtering
-EIGRP over frame-relay
-EIGRP IP bandwidth percent
-EIGRP Named Mode
After learning the subtopics of EIGRP, it would be great if there are a Lab simulation that covers all this topic, maybe 2 or 3? if 1 lab is not possible to cover all. To assess our knowledge if we really know the EIGRP based on CCNP level. So that we can simulate the Lab in GNS3 or real product, and if we solve it then it will prove that we really learned the EIGRP major topic.
Create a Course with basic concepts of Software defined networking.

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 …
Appreciate if you can create some lessons on VPLS.
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

Please discuss the concepts of GRE and IPSec, the pros and cons of each, with an implementation example along with the standard content which you have made for other course topics – basics, troubleshooting, step by step analysis of the packet headers and command outputs.
VIRL has the autonetkit feature which allows for a topology to be preset with criteria. For example, with just a few clicks, IP addresses, OSPF, BGP, etc can be auto created. This allows for skipping the initial time-consuming configs and instead just focusing on advanced key topics, ie BGP, MPLS, PE to CE, etc. Download links for the prebuilt topology can be easily provided to members which they can load up in VIRL. Or instructions on what parameters to choose would work as well.
Though not much but ISP’s and big enterprise network use ISIS. Configuration, Implementation and troubleshooting of IS-IS will be helpful.

CCIE – QoS
first of all, I highly appriciate the simplicity how you are explaining every topic. You are bringing high amount of value. I would recommend to anybody that if they don`t understand some topic, than it is good idea to look on your explanaition for sure 🙂
Anyway, I have studied here QoS and I think that there are few topics missing :
– Queuing (FIFO/WFQ/CBWFQ …. ) it would be nice to have these explained …
– in general it would be nice to have some split in these .. that what is Congestion Management / Conegstion Avoidance .. when and what take places … you know, something in “your style” would be appreciated …
Thank you and wish you luck on your path !
VTI – Both SVTI and DVTI

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.
I don’t found that on this website 😉
the new ccna has ethernetWan – can you add more on that protocol and configurations
Ethernet wan, to my understanding is supposed to replace the MPLS. can you make this subject clear ( I dot see it on the site at all ). thanks.

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?

Show ip route tutorial
Understanding how a network flows reading the show ip route command
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.
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.
ASA SNMP configuration
SNMP configuration on ASA with multiple contexts on failover pairs.
CCIE RS written
Would you add the following topics onto your CCIE RS written lessons?
1) Evolved Technologies
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.
