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: 760 791 850 1517-20 Fixed Classful Subnetting CIDR/VLSM Network Addressing Field >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. > >RFC 760: DoD Standard Internet Protocol (IP), made obsolete by RFC 791, but >still worth reading >RFC 768: User Datagram Protocol (UDP) >RFC 791: Internet Protocol (IP) >RFC 792: Internet Control Message Protocol (ICMP) >RFC 793: Transmission Control Protocol (TCP) >RFC 826: Ethernet Address Resolution Protocol (ARP) >RFC 854: Telnet Protocol Specification >RFC 950: Internet Standard Subnetting Procedure >RFC 959: File Transfer Protocol (FTP) >RFC 1001: Protocol Standard for a NetBIOS Service on TCP/UDP Transport: >Concepts and Facilities >RFC 1002: Protocol Standard for a NetBIOS Service on a TCP/UDP Transport: >Detailed Specifications >RFC 1034: Domain Names - Concepts and Facilities >RFC 1058.
