Ok did a google but could not find a draft on that please forward. So I can
see that is possible for intermediate nodes not necessary to be “SR aware”
I get that but what about the PSP or USP node that removes the SRH EH
header.  I would think that functionality requires that node to be SRv6
aware.

I looked on LSR WG and there is an SRv6 extension for ISIS and OSPF as I
expected. So since there are extensions related to IGP goes back to my
original question of SRv6 aware nodes.
