Yes, both intra-domain and inter-domain routing as well as the
detailed structure of the network layer, i.e. dividing it into 3
sublayers, were developed in OSI.
This is what lead to the idea of using link state locally (for
networks) and distance vector globally (for internets). There was a
good debate on intra-domain routing between a proposal by Dave
Piscatello and Dave Oran. They ended up choosing Oran's, which
became IS-IS. Piscatello's proposal had some interesting properties.
