Applicability Statements:

   IGMP -- The Internet Activities Board intends to move towards general
   adoption of IP multicasting, as a more efficient solution than
   broadcasting for many applications.  The host interface has been
   standardized in RFC-1112; however, multicast-routing gateways are in
   the experimental stage and are not widely available.  An Internet
   host should support all of RFC-1112, except for the IGMP protocol
   itself which is optional; see RFC-1122 for more details.  Even



Internet Activities Board                                      [Page 18]

RFC 1250                     IAB Standards                   August 1991


   without IGMP, implementation of RFC-1112 will provide an important
   advance: IP-layer access to local network multicast addressing.  It
   is expected that IGMP will become recommended for all hosts and
   gateways at some future date.

   SMI, MIB-I, MIB-II SNMP -- The Internet Activities Board recommends
   that all IP and TCP implementations be network manageable.  At the
   current time, this implies implementation of the Internet MIB-I
   (RFC-1156), the extensions in MIB-II (RFC-1213), and at least the
   recommended management protocol SNMP (RFC-1157).

Applicability Statements:

   It is expected that a system will support one or more physical
   networks and for each physical network supported the appropriate
   protocols from the above list must be supported.  That is, it is
   elective to support any particular type of physical network, and for
   the physical networks actually supported it is required that they be
   supported exactly according to the protocols in the above list.  See
   also the Host and Gateway Requirements RFCs for more specific
   information on network-specific ("link layer") protocols.

Applicability Statements:

   RIP -- The Routing Information Protocol (RIP) is widely implemented
   and used in the Internet.  However, both implementors and users
   should be aware that RIP has some serious technical limitations as a
   routing protocol.  The IETF is currently developing several
   candidates for a new standard "open" routing protocol with better
   properties than RIP.  The IAB urges the Internet community to track
   these developments, and to implement the new protocol when it is
   standardized; improved Internet service will result for many users.

   TP-TCP -- As OSI protocols become more widely implemented and used,
   there will be an increasing need to support interoperation with the
   TCP/IP protocols.  The Internet Engineering Task Force is formulating
   strategies for interoperation.  RFC-1006 provides one interoperation
   mode, in which TCP/IP is used to emulate TP0 in order to support OSI
   applications.  Hosts that wish to run OSI connection-oriented
   applications in this mode should use the procedure described in RFC-
   1006.  In the future, the IAB expects that a major portion of the
   Internet will support both TCP/IP and OSI (inter-)network protocols
   in parallel, and it will then be possible to run OSI applications
   across the Internet using full OSI protocol "stacks".

   PPP -- Point to Point Protocol is a method of sending IP over serial
   lines, which are a type of physical network.  It is anticipated that
   PPP will be advanced to the network-specific standard protocol state
   in the future.
