Supported GMPLS Standards

Junos OS substantially supports the following RFCs and Internet drafts, which define standards for Generalized MPLS (GMPLS).

  • RFC 3471, Generalized Multi-Protocol Label Switching (GMPLS) Signaling Functional Description

    Only the following features are supported:

    • Bidirectional LSPs (upstream label only)

    • Control channel separation

    • Generalized label (suggested label only)

    • Generalized label request (bandwidth encoding only)

  • RFC 3473, Generalized Multi-Protocol Label Switching (GMPLS) Signaling Resource ReserVation Protocol-Traffic Engineering (RSVP-TE) Extensions

    Only Section 9, “Fault Handling,” is supported.

  • RFC 4202, Routing Extensions in Support of Generalized Multi-Protocol Label Switching

    Only interface switching is supported.

  • RFC 4206, Label Switched Paths (LSP) Hierarchy with Generalized Multi-Protocol Label Switching (GMPLS) Traffic Engineering (TE)

  • Internet draft draft-ietf-ccamp-gmpls-rsvp-te-ason-02.txt, Generalized MPLS (GMPLS) RSVP-TE Signalling in support of Automatically Switched Optical Network (ASON) (expires January 2005)

  • Internet draft draft-ietf-ccamp-gmpls-sonet-sdh-08.txt, Generalized Multi-Protocol Label Switching Extensions for SONET and SDH Control

    Only S,U,K,L,M-format labels and SONET traffic parameters are supported.

  • Internet draft draft-ietf-ccamp-lmp-10.txt, Link Management Protocol (LMP)

  • Internet draft draft-ietf-ccamp-ospf-gmpls-extensions-12.txt, OSPF Extensions in Support of Generalized Multi-Protocol Label Switching

    The following sub-TLV types for the Link type, link, value (TLV) are not supported:

    • Link Local/Remote Identifiers (type 11)

    • Link Protection Type (type 14)

    • Shared Risk Link Group (SRLG) (type 16)

    The features described in Section 2 of the draft, “Implications on Graceful Restart,” are also not supported.

    The Interface Switching Capability Descriptor (type 15) sub-TLV type is implemented, but only for packet switching.

  • Internet draft draft-ietf-mpls-bundle-04.txt, Link Bundling in MPLS Traffic Engineering
