when add a IP on lo:0 ,then all arp packages can't send out from this computer.
e.g.
#ifconfig lo:0 192.168.1.160 up
then
#arp -a
no any entry.
and the "eth0" can't send any arp packages.
why ?

you should be using a dummy interface
(OT: loopback interfaces in Cisco = dummy interfaces in Linux, if you are configuring quagga, for example)

hi,everyone
I find the answer.
It's due to the netmask. In the lo interface ,I set the netmask as 255.255.255.255 ,then the eth0 works oK
