Hi Primeroz, thanks for your answer.
I set all the carp interfaces, both base and alias, to the 
255.255.255.255 netmask
as you suggested.
This is my netstat now:

...
192.168.10.0/24 link#11            UC          0        0 vlan10
192.168.10.254    link#11            UHLW        2        0 vlan10
192.168.10.10   192.168.10.10    UH          0        0 carp10
192.168.10.11  192.168.10.11    UH          0        0 carp10
192.168.10.12  192.168.10.12    UH          0        0 carp10
...

As you see, the 192.168.10.0/24 is routed through the vlan10 interface, 
and this should be correct.

As before, I can ping 192.168.10.10, but not 192.168.10.11 and above.

Could this be a bug of carp with alias interfaces?

Thanks again.
Giulio.
