alias ip about mon server

[Eric Bond]

I try to setup alias ip on one server, after i copy ifcfg-eth0 and make 
another ifcfg-eth0:0,
I restart network, then ifconfig, it looks like :
lo        Link encap:Local Loopback
        inet addr:127.0.0.1  Bcast:127.255.255.255  Mask:255.0.0.0
        UP BROADCAST LOOPBACK RUNNING  MTU:3584  Metric:1
        RX packets:5088 errors:0 dropped:0 overruns:0
        TX packets:5088 errors:0 dropped:0 overruns:0

eth0    Link encap:10Mbps Ethernet  HWaddr 00:8E:B8:83:19:20
        inet addr:10.0.0.1  Bcast:10.0.0.255  Mask:255.255.255.0
        UP BROADCAST RUNNING  MTU:1500  Metric:1
        RX packets:0 errors:0 dropped:0 overruns:0
        TX packets:0 errors:0 dropped:0 overruns:0
eth0:0      Link encap:10Mbps Ethernet  HWaddr 00:8E:B8:83:19:20
        inet addr:10.0.0.2  Bcast:10.0.0.255  Mask:255.255.255.0
        UP BROADCAST RUNNING PROMISC MULTICAST  MTU:1500  Metric:1
        Interrupt:7 Base address:0x378


when i try to ping eth0:0 ip address through another local computer,it is 
unreachable.
but if i ping eth0's original ip, connection established, why does this 
happen? Something like no other computer knows its alias ip except itself. 
if there are some netfilter or something make this happen?

Thank you.
Eric
