The reason for this is a different one. Interface routes are all added to the routing table. The /32 route for the alias is necessary because the real network is already in the table. Additionally it helps choosing the main interface address for outgoing traffic (instead of an alias) because the network route points to the main interface address. Interface aliases are a bit of a mess because of all these side-effects. -- :wq Claudio
