Standardisation

• Initial proposals for the standardization of
  Frame Relay were presented to the Consultative
  Committee on International Telephone and
  Telegraph (CCITT) in 1984.
• A major development in Frame Relay's history
  occurred in 1990 when Cisco, Digital Equipment
  Corporation (DEC), Northern Telecom, and
  StrataCom formed a consortium to focus on Frame
  Relay technology development. This consortium
  developed a specification that conformed to the
  basic Frame Relay protocol that was being
  discussed in CCITT, but it extended the protocol
  with features that provide additional
  capabilities for complex internetworking
  environments. These Frame Relay extensions are
  referred to collectively as the Local Management
  Interface (LMI).

• Commands
• Router(config-if) encapsulation frame-relay ietf
• This uses the IETF (Internet Engineering Task
  Force) encapsulation, instead of the default
  Cisco encapsulation.
• Router(config-if) frame-relay lmi-type ansi
• This specifies the LMI (Local Management
  Interface) used by the router to talk to the
  Frame Relay switch. The LMI default is Cisco, and
  this overrides that with the ANSI standard
  version.
