INE Routing and Switching Bootcamp Confirmed

I received confirmation this week that the location for the March Routing and Switching bootcamp in Orlando was set so I finally booked my accommodations. I opted not to rent a car since the airport is only about 20 minutes away and it’s a learning trip not a sight seeing trip. Although, my wife will fly in during the weekend in between the two weeks. After a week of 10 – 12 hour brain bombardment that will likely be a much needed...

BGP Outbound Route Filtering

This week I started on the BGP labs and quickly found that there are about 15 different initial...

Automatic creation of a route to Null0 when creating a summarization route in EIGRP is usually a good thing but there will be times where it will cause a loss of connectivity. Keeping this behavior in mind and knowing a few options of how to deal with it will save you some time. In this case R3 is acting as a gateway of last resort by only injecting a default route into EIGRP AS 100 and there is full connectivity between R1, R2 and...

INE Workbook-1 basic L2

I spent a few hours working on the begining of INE Workbook 1 exercises. I got to 1.10 before calling it quits for the day. I worked out a few kinks in the lab like the console connection not working for BB2 and BB3 as well as I was missing CAT5 cables between SW2 and SW3 which was causing some odd results. One of the biggest things I noticed was the need to be able to reference and correlate your network diagram with your physical...
