The kernel can store multiple routes with the same prefix/length, but only one is used for forwarding. Thus when a route is deleted it should be potentially overwritten by a different route in the device's tables. This is why mlxsw stores these nodes. We can have the IPv4/IPv6 code only generate a REPLACE / DELETE notification for routes that are actually used for forwarding and relieve listeners from the need to implement this logic themselves. I think this should work. ?
