Well, when I assign a new IP (for a new subnet) to the same interface 
(using ip route add...),  even though the routing table is updated, it 
still takes about 500ms for the change to happen. This new IP should be 
detected as primary, right? Also, am I right to say that any IP address 
assigned to an alias interface is a secondary IP?
Do you know where the code for the routing cache is?

Thanks for your help,
Andrea
