BSCI Exam Day - Five hours and counting

September 19th, 2008 Bryan Posted in BSCI, IPv6 No Comments »

So here I am with about five hours left until my BSCI exam. Due to fact I have to drive about 40 minutes to the testing site, thanks for stopping your Cisco tests New Horizon, I have about four hours of studying left. Speaking on New Horizon not providing Cisco tests anymore. How can you offer training for the CCNA and CCENT but not provide your customers with a place to take the exam? This seems like bad business to me but obviously they don’t make any money off the testing so it is a risk they are willing to take it seems.

I will be brushing up on redistribution and IPv6, these seem to be my weakest subjects. Funny I say this because I have a feeling at least one if not all of my labs will be in regards to either of these two subjects. I am really looking forward to finishing up this exam, taking the next week off of studying and then diving into the CCIE Security lab exam.

Hopefully my next post is a success story, if not I have the free retake coupon provided by Cisco.

IPv6 A brief introduction

September 8th, 2008 Bryan Posted in BSCI, Cisco, IPv6 1 Comment »

I’m running a little short on time tonight so I am just going to post a few brief facts about IPv6 and will follow up hopefully tomorrow with more detailed information.

  • IPv6 has a 128-bit address size compared to 32-bit for IPv4
  • There are 340,282,366,920,938,463,463,374,607,431,770,000,000 available addresses
  • The addresses are divided into 8 groups of 4 hex characters (2001:0005:0000:0000:0000:0000:0000:0AA9)
  • You can eliminate consecutive zeros by using two colons (2001:0005::0AA9). You can only do this once.
  • You can also drop leading zeros (2001:5::0AA9)
  • Multicast replaces broadcast in IPv6
