Well, depends what you are looking for--current protocols or new proposals. There are two draft requirements documents in the IRTF for next-generation interdomain routing. At a book level, there's John Moy's second OSPF book that comes with a documented application. Alex Zinin's "Cisco IP Routing" is probably the best you'll find on IOS implementation. Volume III of Knuth's "Art of Computer Programming" gives useful background on search algorithms. There's quite a bit out there in published papers. A good start would be to go to www.acm.org, and navigate down to the SIGCOMM proceedings. Also, look through the RFCs for "Implementation Experience" documents. Also, look through www.nanog.org and find work on subsecond convergence, which, IIRC, was first presented at the last Washington meeting. Be aware that you'll need some reasonable understanding of abstract data structures, graph theory, control systems theory, etc., to understand the basis of current work. You certainly can go through the archives of the IETF working groups for each routing protocol and get a good idea how the design consensus evolved. It sometimes feels like the Inter-Domain Routing (IDR) group, which does BGP, is an exercise in herding cats. Sue Hares and Yakov Rekhter, the co-chairs, do a marvelous job of keeping things in a more-or-less consistent direction. OSPF and ISIS are much less controversial!
