Re: OSPF DBDs

I should clarify after reading my own response - I am not suggesting
that OSPF was ever intended to operate on the scale of the global
Internet itself, but as of the time OSPF was developed, that's how
much of the Internet and networks generally speaking were built - on
very low-speed serial links. I believe this likely drove the decision
to exchange DBDs prior to full LSAs - to conserve what were once very
limited bandwidth resources.
