Hi Ron, my read of section 4.1.1 of the draft is the dest opt in your example 
packet would be processed at every segment endpoint.

Subject: [spring] uSID and destination options

C-SID authors,

Consider an SRv6 packet that contains:


  *   An outer IPv6 header
  *   A Destination Options Header
  *   IPv4 payload

The packet does not contain an SRH. However, the Destination Address field  in 
the outer IPv6 header contains a C-SID container and the C-SID container 
contains two or more C-SIDs.

Where are the destination options processed? The following are possible answers 
to this question:


  *   At every segment endpoint node
  *   At the SR path egress node

                                                     Ron
