Secondary ip addressing

[Esanet Services at ESOC]

I would like to know if it is possible to have directed subnet broadcasts
to the multiple subnets on a single physical interface.

Router config would be :

int e 1
ip address aaa.bbb.1.2 255.255.255.0
ip address aaa.bbb.2.2 255.255.255.0 secondary
ip address aaa.bbb.3.2 255.255.255.0 secondary
???

What we would like is to be able to send subnet specific broadcasts from a
separate physical and ip network i.e. a host on int e 2 with IP address
aaa.bbb.10.1 sends broadcast packets to aaa.bbb.1.255 and aaa.bbb.2.255 etc.

Is this possible to set up ?

Thanks

John.
