Les,
Thanks for updating the text. Below are a few proposed changes/additions
to the current text that are mainly to clarify a few things.
Thanks,
Chris
=============
2.4.4. Mapping Server Prefix-SID
The Prefix-SID sub-TLV (suggested value 3) is defined in Section 2.1
and contains the SID/index/label value associated with the prefix and
range. The Prefix-SID SubTLV MUST be present in the SID/Label
Binding TLV.
Proposed last sentence:
The Prefix-SID Sub-TLV MUST be present in the SID/Label Binding TLV unless the
the M-flag is set in the Flags field of the parent TLV.
=============
Existing text:
The SID/Label sub-TLV may be present in the following TLVs/sub-TLVs
defined in this document:
SR Capability (Section 3.1)
SRLB (Section 3.3)
Binding TLV (Section 2.4)
MT Binding TLV (Section 2.5)
Note that when used in the SR Capability and SRLB sub-TLVs the code
point used is the same as the sub-TLV code point assigned by IANA in
the sub-TLVs for TLV 149 and 150 registry.
Proposed text:
The SID/Label sub-TLV may be present in the following TLVs/sub-TLVs
defined in this document:
SR-Capabilities Sub-TLV (Section 3.1)
SR Local Block Sub-TLV (Section 3.3)
SID/Label Binding TLV (Section 2.4)
Multi-Topology SID/Label Binding TLV (Section 2.5)
Note that the code point used for the SID/Label Sub-TLV in the
SR-Capabilities Sub-TLV and the SR Local Block sub-TLV is the same as
the code point used for the SID/Label Sub-TLV in the SID/Label Binding TLV
and the Multi-Topology SID/Label Binding TLV. This code point is assigned
by IANA in the “sub-TLVs for TLV 149 and 150” registry
===============
3.3. SR Local Block Sub-TLV
(add after first paragraph)
The SR Local Block sub-TLV is inserted into the IS-IS Router Capability
TLV-242 that is defined in [RFC7981].
===============
3.3. SR Local Block Sub-TLV
(add after first paragraph)
The SRMS Preference sub-TLV is inserted into the IS-IS Router Capability
TLV-242 that is defined in [RFC7981].
===============
5.3. Sub TLVs for Type 242
…
Description: Segment Routing Local Base (SRLB) <<<< OLD
