First, a general comment on RFC's: when there is an Applicability
Statement, Framework, or Roadmap associated with the protocol
specification, read them first. Some of the more complex families
such as MPLS, IPSec, etc., also have requirements and architecture
documents worth reading.
I would add to these:
RFC 1812 Requirements for IPv4 routers
RFC 1925 The Twelve Networking Truths.
Some RFCs are in major revision, and the drafts may be more useful. I
would recommend BGP students go to the IDR working group page at
http://www.ietf.org and get the most recent draft (I think it's 18,
but it may have gone to a yet newer round). Without false modesty,
also go to the BMWG working group page and get the latest revision of
the terminology for single-router BGP convergence, where we've
cleaned up some of the more confusing BGP terminology. We should
have an updated draft, about ready for RFC, up within a week or two.
RFC 1517-1520 are the fundamental basis for CIDR/VLSM. RFC 1878,
Variable Length Subnet Table For IPv4, has excellent conversion
tables and examples. My RFC 2072 also gives addressing strategies for
renumbering routers.
In fact, here's the timeline for RFCs for IP addressing:
760791 8501517-20
Fixed ClassfulSubnetting CIDR/VLSM
NetworkAddressing

All the April 1st RFCs notwithstanding, the following are classic RFCs that
every network engineer should know about:
And some of the April 1 RFCs are classics that have something to
teach. 1194 is an excellent example of how IP is mapped onto a
specific transmission system.
