Hi WG,



I support the adoption of this draft. I think this is an very useful extension.



There are several comments after reviewing the document:

1) It is mentioned the example of SR-MPLS and SRv6 in the draft. What about IPv6? Is it possible to add an example for IPv6 by leveraging draft-ietf-pce-pcep-extension-native-ip?

[GF]: Yes, this PCEP extension is general, therefore it can also be applied to the scenario of Native IP network. I can mention this point in the next revision of the draft.

2) What is the relation of the IFIT PCEP extension with the companion draft-ietf-idr-sr-policy-ifit which defines the BGP extension to enable IFIT methods for SR policy?

[GF]: For Segment Routing, both PCEP and BGP can be used to instantiate SR Policies, so it makes sense to have the same mechanism for PCEP and BGP. In particular, draft-ietf-idr-sr-policy-ifit simply extends the advertisement of SR Policies in BGP (draft-ietf-idr-segment-routing-te-policy) to include IFIT information. Therefore, this extension is limited to SR-Policy. While, for PCEP, the extension is general and the application to SR Policies is an example.

3) Section 2.1 is about “IFIT for SR Policies” and Section 6 is about “Example of application to SR Policy”. Since the PCEP Extension is general for all path types and SR Policy is just an example, why not merge section 2.1 in section 6?

[GF]: Sure, it can be possible to merge the two sections.



Thanks
