Recommendations for OSPF v3 book?

[Bruce M Simpson]

Does anyone have any good suggestions for a book which discusses OSPF v3 
architecture?

I have read the original John Moy book 'OSPF: Anatomy of an Internet 
routing protocol' but would very much like to know of there is a good 
text out there which discusses OSPF in the wider context of IPv6 and the 
improvements made in version 3 of the protocol.

I should be most grateful for your suggestions.

Kind regards,
BMS
