I've been doing telecom for a long time, entirely familiar with TDM & SONET, etc. For the last two years I've also been working on Ethernet transport over SONET, and I've learned a lot.
I also now realize how little I know about this stuff!
What are my options about learning this more deeply? I know I can start with CCNA level certification, but what are my options? I can read dry books but I suck at learning that way. Online training might be good but I'd like to avoid crappy "schools" and only deal with quality operations. I know I can pay a lot of cash and go to real Cisco schools too.
I also saw mention of Juniper certification, not just Cisco. Others?
Anyway, can I get some help in understanding what my options are in getting on the professional path?
Thanks for any insight offered!
