Have You Stopped Studying for Your CCIE???

CCIE Lab Exam

Many of us might find, that despite our best intentions – we have just gone through a period where we have stopped altogether studying for our CCIE. We are not really sure how it happened…it just did. And the longer we go not studying, feelings of guilt and uneasiness creep in when we think about the concept of starting to study for it again. This really sucks!

Well, we certainly need to do SOMETHING! Check out this amazing video from Network Chuck! It might be just the ticket we need to getting that bus started up and rolling again!

CompTIA A+ 220-901 and 220-902 Retiring July 31, 2019

March 26, 2019 at 10:29 pm

CompTIA A+

OK, OK, I know, we don’t like deadlines, but for my readers that are in the middle of their CompTIA A+ prep, it is time to start marking the calendar. The 220-901 and 220-902 exams for CompTIA A+ certification are no longer offered after July 31, 2019.

Time flies when you are having fun studying right? Be sure to dive in and clear these exams well before the retirement date. Remember, we have two courses for you (one for each exam) at CBT Nuggets. These courses include valuable tools like Flash Cards, Hands-On Labs, and Quiz Questions to make sure you master the material.

BGP Processes in the Cisco IOS

August 21, 2018 at 10:32 am

BGP

These are some notes that I used to help teach a recent module in my upcoming Border Gateway Protocol (BGP) – Cisco Routing Policy Mechanisms course at CBT Nuggets. Enjoy!

There are many processes that work together to provide BGP services in the Cisco IOS. To see those that are running on your IOS version (and hardware), run the following command:

show processes cpu | include BGP

There are four core processes you should definitely see:

  • I/O – this process is responsible for moving prefixes in and out of the appropriate InQ and OutQ mechanisms; this allows us to both send and receive prefix information
  • Router – this process is the workhorse of the BGP system and takes care of policy application and the BGP Best Path Decision Algorithm
  • Scanner – the scanner process defaults to one minute intervals of operation; you can change this with the bgp scan-time command under the BGP configuration; this process is scanning for changes that might require a revamp of the BGP information (an example would be a prefix removal due to next hop reachability issues)
  • Scheduler – this process is responsible for scheduling the various BGP processes that might be running

To see the Scanner process in action – you can use the command – debug ip bgp events

Remember, you might see other BGP related processes running on your system. Cisco is constantly working hard on their implementation to improve efficiency and reduce CPU workloads. For example, you might see:

  • BMP Server – this service permits the functionality of BGP Monitoring Protocol for neighborships
  • Event – this service helps the Scanner with its potential workload – it quickly responds to events like network statement introduction and redistribution commands
  • NHT – a next hop tracker process that, again, assists the Scanner service with its work
  • Open – you might get lucky and catch a glimpse of this process – it exists to assist with neighbor formation
