Re: [spring] Is srv6 PSP a good idea

[Robert Raszuk <[e-mail]>]

Hey Sander,

No worries ... three IPv6 musketeers have already presented themselves well
to this discussion. This was just one more demo of it. No need to apologize
- at least me :)

And while you can call someone's opinion the way you like - the fact that
SRv6 builds on top of IPv6 does not make it automatically IPv6 extension.

My perhaps subtle point was that while politically it has been sold like
minor IPv6 extension from technical point it does not need to be
positioned like one. The sole fact that it reuses the same ethertype does
not make it an extension.

Now as I have already been through my round of circular explanations in the
previous months - now I just sit and watch how it goes round and round
again.

Best,
R.,
