"I'm trying to work around this with dhcp6.  However, I seem to be stuck at providing a router address.  Does dhcp6 support the router address option?  If so, how?"

Sybex Cisco Certified Network Associate book. Wait before buying

I have been studying this book with the intent of obtaining Cisco CCNA certification.  However, I noticed several errors in the chapter on IPv6.  I have been in contact with the author about this and he said he will be updating that chapter to correct the errors I pointed out.  I have the Deluxe Edition, 6th edition, revised and updated for 2011, but I believe the errors may also be in the 7th edition.  So, if it's on the shelf now, it will likely contain those errors.  Wait for one with a…

Good IPv6 reference book

I have noticed that many problems people experience are due to not understanding IPv6 and how it differs from IPv4.  There is one book that contains a lot of useful IPv6 information.  It is IPv6 Essentials, by Sylvia Hagen and published by O'Reilly.  It's available in both paper and e-book versions.  What's nice about the e-book version is purchasers are entitled to free updates.  I refer to this book…
