Hi Med, Good point. Omitting the IE would work as well.

Shouldn't this just work if srhIPv6Section is omitted when there is no SRH?

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.
