Being a fairly early bird when registering I was among one of the first being able to select which techtorials, labs, panels, etc. to participate in. This year, I decided to mix some SP and DC stuff instead of doing only one track. The day before the conference really starts there are usually either half or full day techtorials/labtorials which either means "passively listen to the presenter(s)" or "lab like hell" - previously I've enjoyed myself immensely by "passing" the CCIE R&S prep (~ 7 hrs actual lab) and CCIE SP prep (~7 hrs actual lab) to see what the skill level and makeup of the real test would be like. 2010 I decided to skip that stuff and instead go and and get a L2VPN refresher in TECMPL-3001 (Title Layer 2 Virtual Private Networks - Converged IP/MPLS Network) as I don't tend to do much of L2VPN nowadays.
The techtorial was divided in three parts each having its own lecturer. Part 1 consisted of your basic L2VPN setup, how it works, etc. Part 2 was VPLS for dummies and Part 3 with future enhancements such as PBB/802.1ah, H-VPLS with PBB, etc. Future products such as ME3600X/ME3800X were briefly mentioned and presented as well. All three speakers were pretty experienced and I think all from a BU.
All in all a good day.
