Hello list.
I'm running Mandrake 9.1, two NICs bonded to a single IP.

Hi,
leaving aside for a moment the question about why i might wish to do such a

IP address, my machine (RH6.1, 2.2.5-20smp kernel) starts responding to
ARP requests for that IP address. this is true even if i configure
I found some strange problem on RH6.1
when I setup loopback interfase
ifconfig lo:1 xxx.xxx.xxx.xxx netmask 255.255.255.255 up
and made
ifconfig -arp lo:1 ,loopback continue respond to ping.
What is the problem. Bug
