The table below is from a document I'm working on, but I think it's a
good format for a study guide. Unfortunately, Cisco tends to list
all RFCs with which a release is compliant, but not always all I-D's
and often not what feature the document applies to. Do note that
some of the I-D's in the table may have expired or moved to a later
version or RFC.
Sorry for the formatting, but it might be useful for BGP study.

a level beyond this can be searching the archives of the relevant
IETF WG (in this case, IDR) and seeing how the decision was made to
implement the feature.
