Robert,
Even then, the core SP router may ignore the PSSI.
Recall that the first two bits of the PSSI option are 00. This means that if
the processing node doesn’t recognize the PSSI, or is configured to ignore the
PSSI, it will simple skip over the PSSI.
In most cases, core SP routers will be configured to ignore the PSSI.

Hi Ron,
No one is questioning that. If packet's destination is not a local address of a
router all options can be ignored.
Fun however starts when destination address in the packet *is* a local address
on the router ie. the router is acting as Segment Endpoint.
Thx,
R.

Likewise, SP core routers would ignore the PSSI and wouldn’t even see the PPSI.

SRv6 does not require TLV processing for normal forwarding (use case: SP core).
