Implement and troubleshoot layer 2 protocols + Doc Links

Implement and troubleshoot layer 2 protocols

I’m currently working towards the CCIE Routing and Switching Lab Exam version 5.0 and I’m following on from the Cisco provided blueprint. Below are a portion of the sub topics I’m currently studying that align with the Cisco blueprint. I’ve also linked to the relevant page in the documentation. This is the same documentation available to exam candidates in the exam.

I’m often trying to find where each of the topics from the CCIE R&S Blueprint is within the Cisco documentation (aka Cisco DocCD) so I can quickly find what I need in the Lab Exam, some topics are pretty straightforward and some take me a while to find. I’ll outline more topics as I work through the Blueprint. I also plan to add my own studynotes to go along with the official documentation. Let me know if you see any errors or omissions.

Next up, Implement and troubleshoot layer 2 protocols and Implement and troubleshoot VLANS.

Choosing firmware for Draytek ADSL Routers

I recently stumbled upon the firmware page for the Draytek DV120 after having an issue with stable connectivity – http://www.draytek.com.au/downloads.php?type=Vigor120. The manufacturer makes available 10 varieties of the same version of firmware with no guidance as to how we should be choosing firmware for Draytek ADSL Routers.

After contacting various suppliers of Draytek worldwide and discussions with Telco’s in New Zealand I’ve found that two main chipset DSLAMs exist at the moment. Broadcomm chipset based DSLAMs are used in older installations and the Ikanos chipset isused in the dual personality A/VDSL DSLAMs within Chorus cabinets.
