Cisco CCNP and CCIE Study Notes

Cisco publishes a nice technical magazine called The Internet Protocol Journal that usually has interesting articles about both deployed networking technologies and also future work-in-progress type stuff. All the back issues are available on the web and they also have a free subscription in case you prefer hard-copy. Such reading may not look directly relevant to the CCIE or CCNP exam but it sure helps to round out one's networking knowledge in general. The journal also has a book review section that sometimes brings attention to good books in the networking area.
