The NSFNET backbone along with the various NSF sponsored regional networks as well as other research networks were quite a challenge to glue together, with somewhat ill-defined borders between networks and IGP domains that spanned multiple networks and their administrators. A better tool was desperately needed.
One of the most entertaining moments in my history of IETF involvement
was when Hans-Werner Braun and I explained NSFNet and ARPAnet routing
interworking. Everything was still hierarchical so we did it all with
RIP and a lot of following default routes. Dave Clark slapped his
forehead. Jon Postel just shook his head. Yes we needed something
like BGP but that took a few years.
