[Lsr] draft-zhu-lsr-isis-sr-vtn-flexalgo-01

Hi Authors,

    I have the following comments/questions on the draft.

    In section 2 "Advertisement of SR VTN Topology Attribute",
for the last sentence "..., the Flex-Algo identifier could be reused
as the identifier of the VTN in control plane.",

    How do you reuse the Flex-Algo identifier?
    Does every VTN have a Flex-Algo identifier?
    If so, where does the Flex-Algo identifier of every VTN come from?

    In section 3 "Advertisement of SR VTN Resource Attribute",
    is new flag "V" (Virtual) defined in this draft as an extension to RFC 8668?

    If so, should an IANA request/action in section "IANA Considerations"
be added for this extension?

    If not (i.e., it is defined in another draft),
it is better to remove the definition of flag "V" from
this draft and add a reference to another draft.
    In this case, it seems that there is no IANA request from this draft.
It would be better to change the intended status of the draft from
the standards track to informational.

Some nits:
In section 2, the second sentence of the last paragraph,
should "to used" be changed to "to use"?

In section 3, the first sentence of the second paragraph,
should "was defined to advertise" be changed to
"defines the advertisement of"?

Best Regards,
Huaimo
