Hi Linda,

Thanks for your review.

The draft is correct about the Calculation Type being between 0-127. This is derived from the underlying IGPs. Please refer to the IGP specification (specifically https://datatracker.ietf.org/doc/html/draft-ietf-lsr-flex-algo-17#section-5) in this regards.

Thanks,
Ketan

Ketan, Peter, Shawn, Gaurav,

Section 3 of the draft-ietf-idr-bgp-is-flex-algo-07 specifies the Calculation-Type as between 0-127. But the IANA sites shows that  IGP Algorithm Types has 2-127 unassigned, and 128-255 assigned to Flex Algorithm.

2-127

Is it correct?

See:

This WG LC does not include any other section of the draft.

The WG should consider:
1) Is section 3.6 ready for publication,
2) Does section 3.6 help the IDR draft match the LSR draft?
3) Does this addition help deployments?

All authors need to resend their IPR statements for -07.txt to the list.
