CCNA (200-301) Topic 6.6: Puppet, Chef, and Ansible

 

This video is a sample from our CCNA (200-301) Video Training Series, and it gives us a high-level overview of three configuration management utilities: Puppet, Chef, and Ansible. These are new network programmability topics added to this version of Cisco’s CCNA exam.

 

It’s interesting that the verb used by the exam blueprint isn’t configure, troubleshoot, or explain, it’s to “recognize the capabilities of” these tools. So there’s no need to have programming knowledge of these tools for the CCNA exam.

What I'm Thankful for This Year

kw train Nov 26, 2020

As we approach Thanksgiving Day here in the states, I've been reflecting on what I'm thankful for this year. Even though 2020 has been a very unique year, I'm thankful for lots of good things that have happened. Here are just a few examples: 

  • My youngest daughter got married to a wonderful young man who we love like a son.
  • We added another member (Mariam Said) to our KWTrain team.
  • My family members (each of whom I love and am grateful for) are happy and healthy.
  • And I'm thankful for YOU. Although this year has been a challenging one for many businesses, you've continued to look to us to help you advance your IT career. 

I pray that each of you have a blessed holiday season.

With a grateful heart,

Kevin

OSPF Advanced Concepts - Part 4

ccie r/s ccna r/s ccnp r/s Sep 24, 2019

In the previous part of our OSPF series, we examined options for manually filtering routes. As we wrap up our look at advanced OSPF topics, we'll discuss default routes, and compare OSPFv2 with OSPFv3.

Default Routes

We have seen where OSPF can automatically generate a default route when needed. This occurs with some of our special area types. For example, of you configure a totally stubby area, of course a default route is required and OSPF generates this route automatically from the ABR.

In order to increase flexibility with your designs, default routes injected into a normal area can be originated by any OSPF router. To generate a default route, you use the default-information originate command.

This command presents two options:

  • You can advertise 0.0.0.0 into the OSPF domain, provided the advertising router already has a default route.
  • You can advertise 0.0.0.0 regardless of whether the advertising router already has a default route. This second method is accomplished...

OSPF Advanced Concepts - Part 3

ccie r/s ccna r/s ccnp r/s Sep 10, 2019

In our previous blog post, we examined how OSPF can automatically filter routes through the use of special areas and LSA Types. But what about your options for manually filtering routes in OSPF? In this post, we will examine techniques that you can use at various points in the topology.

Filtering at the ASBR

One simple and effective method of filtering at the ASBR is the use of a distribute list. Here, we define the rules for route identification with an access list, and then reference this access list in the distribute list. 

Figure 1 - OSPF Topology

In this example, our Area 1 is configured as a normal, non-backbone area. You can clearly see this when you examine the routing table on ORL.

Note the two prefixes (E2) of 192.168.10.0 and 192.168.20.0. Let’s filter 192.168.10.0 at the ASBR of ATL.

Note how simple this configuration is. Let’s see if it worked by examining the route table of ORL once again:

The configuration worked perfectly and...
