Title says it all really!
Today I passed the QoS exam, which was the last one I needed for CCIP certification. Just got to wait for the official confirmation now.
I mainly used the Cisco QoS Exam Certification Guide 2nd ed for self study, and referenced other material from the Cisco website.
Good luck to those of you preparing for exams in the near future!
Thanks for all the nice messages everyone.
As for what's next, I'm giving it some thought over the weekend.
I know that I'll be concentrating more on the IPv6 side of things. Also, maybe some datacentre oriented study. Many years ago I had a background in servers, so it could be good to see what's going on there these days.
