Hi Ron

I don’t think you are really asking equipment vendors to provide that information on this list.  That will not happen.

I’ll simply repeat what has been stated by others on this list.
Products with limited ability to receive and process a packet containing a RH when SL==0 exist.
PSP provides a means of allowing those products to be used as a PE.

Thanks
  Darren

Andy,

AFAIKS, the only use case PSP is to accommodate SRv6 egress nodes that:


  *   Can process an SRv6  SID that appears in the IPv6 Destination Address
  *   Can process the SRH with Segments Left equal to 0
  *   But cannot process the SRH with Segments Left equal to 0 at high speed


I am not aware that any such device exists. Does anybody know of one?

Subject: Re: [spring] WGLC - draft-ietf-spring-srv6-network-programming

MPLS PHP was invented to solve a particular issue with some forwarding engines at the time - they couldn't do a final pop followed by an IP lookup and forward operation in a single forwarding cycle (it would impact forwarding speed by 50% best case). 20 years later, is this still an issue at the hardware/firmware level? If so, affected implementers should speak up, otherwise there's really no need for PSP.

Cheers,
Andy (who was there at the time)

Hi Ron,

Purely looking at technical aspect that is not true at all.

MPLS PHP does not remove label stack. MPLS PHP is just used to pop last label. After MPLS PHP packets continue with remaining label stack to the egress LSR (example L3VPN PE).

>  I don't think that you can compare MPLS PHP with SRv6 PSP

But I agree with that. Both operations have very little in common from packet's standpoint or forwarding apect. Well maybe except "penultimate" word :)

Kind regards,
R.

Folks,

I don't think that you can compare MPLS PHP with SRv6 PSP. MPLS PHP is a clear case of de-encapsulation. We do that all the time. In SRv6 PSP, we are removing something from the middle of a packet. That is quite a different story.
