I am reviewing  draft-ietf-bier-isis-extensions-07 on behalf of the ops
directorate in an effort to ensure attention to operational considerations. 
This document defines a new sub-TLV for IS-IS for use with BIER.  It also
defines an IANA registry for additional sub-sub-TLVs for this new BIER sub-TLV.
 Overall, this document is ready with some nits.

The only substantive comment I have is in section 5.6 regarding reporting
misconfigurations.  What is not stated is _how_ this is to be done.  There is
no reference to a standard BIER or IS-IS mechanism with how this reporting
should be carried out.  For operational consistency, I feel some guidance
should be offered.

The one nit I noticed is in section 6.2:


Label ranges in multiple sub-sub-TLV MUST NOT overlap.


Label ranges in multiple sub-sub-TLVs MUST NOT overlap.
