So as UPA is generated by ABRs now ABRs must be locator aware.

locator is a prefix, just advertised in a different TLV.


Moreover local flooding must be able to map nodes to locators and locators must be flooded in the underlay.

I'm not sure what is your point, locator processing is equal to any other prefix processing on ABR.


If one wants to tunnel flex-algo's between POPs across base (say core not being flex-algo aware) this is not possible to still use UPA ?

sure, in which case the protocol that runs over tunnel would be different than the protocol that provides the underlay for the tunnel.
