in this direction. IIRC the problem isn't to do with the route annoucements,
it's the route withdrawals. I believe BGP only specifies the prefix being
withdrawn and not the path, so if it's advertised multiple paths to a prefix
it's impossible to know which has been withdrawn.


That is 100% correct, yes.  Selective withdrawal is not supported.


Wouldn't Equal Cost Multi-Path (ECMP) solve this?
