I think we should let this be a global knob, and then pick it up on all interfaces we classify as "underlay", so uplinks, mlag peer links and l3_edge/core_interfaces where include_in_underlay_protocol has been set.

@ClausHolbechArista Maybe fine. It does simplify applying multicast static config on systems dedicated for static multicast.
But in systems that uses both static multicast and pim sparse mode, there should be a way to not apply the multicast static on links dedicated to pim sparse mode as well.
