Hi Zafar,

Correct. For instance next free value 6 for SID at IPFIX entity 46.

We have seen vendor implementation marking 5 even though the label value is a SID, not coming from LDP. This due to the fact that there is no value assigned for SID yet.

Best Wishes
Thomas Graf

Hi Thomas

Did you mean there is a need for IPFIX MPLS label type entry for Binding SID?
Can you please elaborate?

Thanks

Regards ... Zafar

Dear Zafar, Dear draft authors,

I reviewed draft-ali-spring-sr-traffic-accounting-04 and tested it in Swisscom's lab. Planning to deploy it in the production network in the coming months.

The draft is very straight forward and easy to read. I have only one small comment regarding section 7, IANA Considerations.

In IPFIX entity type 46 at IANA, the top label type (label source) is defined. In the following section the possible values are described:
https://www.iana.org/assignments/ipfix/ipfix.xhtml#ipfix-mpls-label-type<https://eur03.safelinks.protection.outlook.com/?url=https%3A%2F%2Fwww.iana.org%2Fassignments%2Fipfix%2Fipfix.xhtml%23ipfix-mpls-label-type&data=02%7C01%7CThomas.Graf%40swisscom.com%7C77d5d2926dba439191fd08d7bdeefdaf%7C364e5b87c1c7420d9beec35d19b557a1%7C1%7C0%7C637186706461423641&sdata=l2ZfUq0PHaTGFQCHwfsaFL7jKT0CGorn9QpBo4OKy1A%3D&reserved=0>

For Segment Routing an additional value needs to be defined and your draft seems to be the right place to cover that.

Hope that makes sense.

Best Wishes
Thomas Graf
