Intermediate System to Intermediate System (IS-IS) Extensions in Support of Generalized Multi-Protocol Label Switching (GMPLS)
draft-ietf-isis-gmpls-extensions-19
Technical Summary
This document specifies additional IS-IS link attributes required to
support GMPLS.
Working Group Summary
The document has been extensively discussed in and reviewed by the WG.
The WG had consensus on progressing the spec.
Protocol Quality
The document has been reviewed for the IESG by Alex Zinin.
RFC Editor Note:
Section 5. "Security Considerations"
OLD:
This document specifies the contents of GMPLS TE TLVs in ISIS. As
these TLVs are not used for SPF computation or normal routing, the
extensions specified here have no direct effect on IP routing.
Tampering with GMPLS TE TLVs may have an effect on the underlying
transport (optical and/or SONET-SDH) network. Mechanisms to secure
ISIS Link State PDUs and/or the TE TLVs can be used to secure the
GMPLS TE TLVs as well.
