Hi Med,

Good point.
Omitting the IE would work as well.

Hi Thomas,

Why sending a zero length array  is needed especially that the decompression is 
done at the data collector? Shouldn't this just work if srhIPv6Section is
omitted when there is no SRH?

Cheers,
Med

Dear John,

My apology. Your assumption is correct. 

In case when the compressed SID container is only used in the IPv6 destination 
address of the provider data plane and the SRH is not being present at all, it 
would be a zero lenght array.

Best wishes
Thomas
