Description of Problem:
 Both of the LOMs (LAN-on-Motherboard, or onboard NICs) are responding to ARP 
requests for each of the LOMs on the (forthcoming Dell) system.

If an ARP request is made to either of the LOMs for an IP address either of the 
LOMs has it responds as the owner.

This leads to corruption of the ARP tables on switches wherein VLANning is 
employed and the server spans both VLANs.

Attached are the logs from the switch, and from TCP/IP sniffing

UPDATE - Thomas Chenault 1/02/02
I have tested for this condition using other servers and NICs (Intel and 
Broadcom) and found the behavior to be the same. Both Red Hat 7.1 and 7.2 
behave as described above, responding to ARP requests on all receiving 
interfaces. 

I am aware of two circumstances under which the behavior can be observed:
   1) when pinging from a switch to a server which exposes multiple physical
       interfaces to the switch (as described in this issue).
   2) when multiple physical interfaces are exposed to a single physical subnet
       which is divided into multiple logical subnets.

I will begin discussions with our Linux team. I recommend that:
   1) the issue be moved from the Dagger bucket to the Linux bucket.
   2) the issue be lowered to sev. 3 due to limited impact.

UPDATE - Thomas Chenault 1/07/02
I have confirmed that the behavior is the same when with Red Hat 7.0 (2.2 
kernel). 

Version-Release number of selected component (if applicable):
Red Hat Linux 7.0, 7.1 SBE, 7.2.


How Reproducible:
Always

Steps to Reproduce:
1. See above
2. 
3. 

Actual Results:
ARP requests for other NICs on multihomed system are responded to.

Expected Results:
No ARP responses for the other NICs should be sent.
