folks looking into RIF's might want to check out Fred Ingham's paper, found in the Groupstudy referece lists:
http://www.groupstudy.com/notes/notepages/rif2.html the field in question is the total length of the RIF. Much as I hate to say it publicly, Sybex and Todd Lammle books of late have been of very poor quality. The text is filled with errors, many of which are pretty basic. I have good reason to believe that Sybex puts a very low value on the technical review process, which is supposed to catch all these errors. But to be truthful, things like this shouldn't be showing up anyway. It's not real hard to doublecheck facts, like what the RIF length field does, and whether or not a domain with a single OSPF area requires an area 0 or not. I'd take Rossi and Ingham over Lammle every time, especiall over the last year or so.
