Tony, Kireeti,

So “I do not want to modify my current implementation” is the argument to stop people interested in Bruno’s draft from using it?
If such HW can/ need be modified to implement the new complex encoding scheme you proposed, why it cannot implement simple encoding in Bruno’s draft?

Please also look at  https://datatracker.ietf.org/doc/html/draft-decraene-mpls-slid-encoded-entropy-label-id-04#section-4.4 and https://datatracker.ietf.org/doc/html/draft-decraene-mpls-slid-encoded-entropy-label-id-04#section-4.5

Thanks

Regards … Zafar

Subject: Re: [mpls] Poll 2: New SPL vs re-purposed ELI for carrying Network Action Indicators





The draft has been implemented for the exact (SLID) use-case on hardware platforms based on Broadcom Jericho2 family of ASIC
Please take a look at https://datatracker.ietf.org/doc/html/draft-decraene-mpls-slid-encoded-entropy-label-id-04#section-7
No such issue was noted


And Jericho2 is the only thing that counts in the entire world?
