Study Update # 6

I started today off really early by finishing up the Frame-Relay chapter at around 7 A.M. but you know what they say about the early bird! I started by creating by far the most complex lab routing scenario so far. Using GNS3 I created a hybrid 5 router Frame-Relay topology using the OSPF protocols with two different areas. Needless to say it took me a while however I couldn't figure out why my full-mesh couldn't talk to my point-to-point connections. I know it had to do with the router that was the ABR (Area Border Router) i just had a lot of stuff to cover today so i didn't dwell on it to much.

From there I read some troubleshooting scenarios envolving Frame-Relay and I have to say this. After 3 days of Frame-Relay study it's still the only topic I'm not confident that I know at least 80% of the material. With that being said I'm going to have to spend some extra time getting this down. I've read a few forums and a lot of people would agree that Frame-Relay is the hardest to grasp. Mainly because there's a lot of Layer 2 and 3 protocols that go hand and hand so it's easy to get confused. Also it's not the easiest lab to setup so just that along takes some time. I went over the VPN chapter which was a lot of info I already knew but was good review. It was also the only chpater to have less than 20 pages (only had 10). Next up is NAT and IPv6 then it's crunch time were I get everything down good and prepare for the test!
