Err, no. OSPF was not a descendant of IS-IS - it was a separate development,
based mainly on the ARPANET's original link state routing. (I can't recall if
John Moy and I took a lot from the later 'area' version of the ARPANET link
state, although we knew of it.) I think we became aware of IS-IS as OSPF
progressed, and IIRC John 'borrowed' a few ideas (maybe the sequence number
thing).
IS-IS was later evolved to handle both OSI and IP addresses (and has, I
assume, since been extended to handle IPv6 too).
