Supported IPv4, TCP, and UDP Standards

Junos OS substantially supports the following RFCs, which define standards for IP version 4 (IPv4), Transmission Control Protocol (TCP), and User Datagram Protocol (UDP).

  • RFC 768, User Datagram Protocol

  • RFC 791, INTERNET PROTOCOL - DARPA INTERNET PROGRAM PROTOCOL SPECIFICATION

  • RFC 792, INTERNET CONTROL MESSAGE PROTOCOL - DARPA INTERNET PROGRAM PROTOCOL SPECIFICATION

  • RFC 793, TRANSMISSION CONTROL PROTOCOL - DARPA INTERNET PROGRAM PROTOCOL SPECIFICATION

  • RFC 826, Ethernet Address Resolution Protocol—or—Converting Network Protocol Addresses to 48.bit Ethernet Address for Transmission on Ethernet Hardware

  • RFC 854, TELNET PROTOCOL SPECIFICATION

  • RFC 855, TELNET OPTION SPECIFICATIONS

  • RFC 856, TELNET BINARY TRANSMISSION

    To transmit using an 8-bit binary path, use the telnet host 8bit command, where host is the name or address of the remote system.

  • RFC 862, Echo Protocol

  • RFC 863, Discard Protocol

  • RFC 894, A Standard for the Transmission of IP Datagrams over Ethernet Networks

  • RFC 896, Congestion Control in IP/TCP Internetworks

  • RFC 903, A Reverse Address Resolution Protocol

  • RFC 919, BROADCASTING INTERNET DATAGRAMS

  • RFC 922, BROADCASTING INTERNET DATAGRAMS IN THE PRESENCE OF SUBNETS

  • RFC 950, Internet Standard Subnetting Procedure

  • RFC 959, FILE TRANSFER PROTOCOL (FTP)

  • RFC 1027, Using ARP to Implement Transparent Subnet Gateways

  • RFC 1042, A Standard for the Transmission of IP Datagrams over IEEE 802 Networks

  • RFC 1157, A Simple Network Management Protocol (SNMP)

  • RFC 1166, INTERNET NUMBERS

  • RFC 1195, Use of OSI IS-IS for Routing in TCP/IP and Dual Environments

  • RFC 1256, ICMP Router Discovery Messages

  • RFC 1305, Network Time Protocol (Version 3) Specification, Implementation and Analysis

  • RFC 1519, Classless Inter-Domain Routing (CIDR): an Address Assignment and Aggregation Strategy

  • RFC 1812, Requirements for IP Version 4 Routers

  • RFC 2338, Virtual Router Redundancy Protocol (obsoleted by RFC 3768 in April 2004)

  • RFC 2873, TCP Processing of the IPv4 Precedence Field

  • RFC 3021, Using 31-Bit Prefixes on IPv4 Point-to-Point Links

  • RFC 3246, An Expedited Forwarding PHB (Per-Hop Behavior)

  • RFC 3768, Virtual Router Redundancy Protocol (VRRP)

  • RFC 4884 Extended ICMP to Support Multi-Part Messages

    Note:

    In Junos OS, support not available for setting the length attribute.

  • RFC 5798, Virtual Router Redundancy Protocol (VRRP) Version 3 for IPv4 and IPv6

  • RFC 5925, The TCP Authentication Option

    TCP-based features are fully supported. Master Key Tuple/ key management is Junos specific. The CLI/application uses Junos keychain infrastructure for MKT configuration.

  • RFC 6527, Definitions of Managed Objects for the Virtual Router Redundancy Protocol Version 3 (VRRPv3)

    The following features are not supported:

    • Row creation

    • Set operation

    • vrrpv3StatisticsRowDiscontinuityTime MIB object

    • vrrpv3StatisticsPacketLengthErrors MIB object

  • RFC 8335, PROBE: A Utility for Probing Interfaces

The following RFCs do not define standards, but provide information about IP, TCP, UDP, and related technologies. The IETF classifies them as “Informational.”

  • RFC 1878, Variable Length Subnet Table For IPv4

  • RFC 1948, Defending Against Sequence Number Attacks
