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

Hi,

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

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 …
– WRED
– 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 …

GETVPN

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.

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.

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.

ipV6 OSPFv3 LSA Types and how they compare to ipV4 OSPFv2.

I wondered if we could have a topic explaining in more detail the LSA types in ipV6 and how they compare to ipv4. There are two additional types in ipV6 that I’m aware of. More detail would be helpful. Also the name of the types appear different.

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.

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.

Possible Topic – Network Troubleshooting Using Linux

Good evening. At my workplace, we have the opportunity to access end systems for troubleshooting purposes when there the supposed ‘looks like a network issue’ present. As a result, we can login to *nix hosts and trace packets from source to destination. What I am recommending as a subject, is your opinion concerning what you find to be very useful tools for troubleshooting connectivity. For example:
– route -n
– netstat
– tcpdump
– wget
– traceroute/tracepath
– curl
– etc.
