* How can E be on the SRv6 SID list if it did not advertise SRv6
participation in the first place ?

* What do you mean by "SRv6 SID in FA 128" ? Aren't SIDs global and not per
FA ?

Btw this is good discussion but how is this related to IP Flex Algo
topic/draft ?

Last - I do share your concern on how topology computation can be data
plane independent. Yes it works for IP Flex Algo when IPv4 and IPv6 are
topologically congruent, but when you add running SR on subset of nodes to
the mix it is no longer the case.

Thx,
R.
