# Shepherd Reviews for draft-ietf-idr-sr-policy-path-mtu-10 (you can also see it at: https://wiki.ietf.org/e/en/group/idr/Shepherd-SR-BGP-LS/BGP-SR/draft-ietf-idr-sr-policy-path-mtu ## Review -10 Summary: Revision 10 resolves all the issues listed in the shepherd report for draft-ietf-idr-sr-policy-path-mtu-10. This report examines the document in terms of the TEA template checklist for Sub-TLVs (see https://wiki.ietf.org/group/idr/TEA-templates/SubTLV) Technical issues ------------------- Issue-1: Specify IANA assignments in TBDnnn format, in section 3 + 6 Section 3: Old text: /Type: to be assigned by IANA./ New text: /Type: TBD1 (to be assigned by IANA). Section 6: Old text:/ TBA Path MTU sub-TLV This document New text:/ TBD1 Path MTU sub-TLV This document/ Issue-2 - Sub-TLV link to TLVs in TEA Can the Path-MTU appear in any other TEA TLV than SR Policy? I believe the answer is "no", but the document needs to state New text for section 4:/ "This document specifies the Path-MTU Sub-TLV to appear only in the SR Policy TLV of the Tunnel Encapsulation Attribute (TEA). Any other use of the Path-MTU sub-TLV is outside the scope of this document. / Issue-3 - Section 4, Does this Sub-TLV play a part of the validation Please state clearly that this Sub-TLV does not play a part of BGP's validation of this Tunnel. current text:/ The consumer of the SR policies is not the BGP process. The operation of sending information to consumers is out of scope of this document./ New text:/ The consumer of the SR policies is not the BGP process. The bgp process does not validate the tunnel based on the SR Policy information (including the Path MTU Sub-TLV). The operation of sending information to consumers is out of scope of this document. / Issue-4: Missing Manageability section Please add an section to indicate how operators may manage set or monitor the PATH MTU via existing Yang modules or BGP-LS support. If these do not exist, suggest whether a yang module or BGP-LS support would be useful.
