Hi Ketan,
Thanks a lot for the feedback. So far Sergey feedbacked in favor to keep IE46
and SrSidType being separate. Lets see which opinion others have on the list.

Hi Ketan,
Thank you very much for the feedback.
[KT] Why not extend the existing IPFIX MPLS Label Type (value 46) to add SR
Prefix SID, SR Adjacency SID, SR Binding SID ... (basically the segment types
from RFC8402)? It's a simpler change to an existing element/field that makes it
easier for r

I should have been more clear in my email.
The proposal/suggestion is to add the following to the IPFIX MPLS Label type

I agree with Kethan and Jeff.
This draft is extending IPFIX defined in RFC 7011 7012 to support SR
segments over IP export.
Since SR-MPLS reuses the MPLS data plane, why would the existing IPFIX RFCs
also not support SR-MPLS without having to dig into IGP control plane
extensions as from an IPFIX
In general, I agree with what Ketan said, what’s important - it is the value
that is being used in forwarding, even if multiple control plane entries exist,
think about IGP migrations, or LDP to SR, where more than 1 protocol could be
distributing the labels/SIDs. I’m not sure the FIB is the rig
