I was seeing arp entries on dom0 for itself using this mac address,
oddly enough I do not see this any more with

The whole time I thought this was expected behavior. Was something
changed recently that would affect this? I was seeing the identical
behavior on both my SMP and UP machines until today. Got to the point
where I was using bgp to route local host traffic through my gateway to
get the two dom0 peth0's tp talk to each other.



dom0-1 - 10 domU
dom0-2 -  3 domU
           

                Gateway
                   |
      --------------------------  subnet A
         |                 |
     dom0-1              dom0-2
         |peth0            |peth0            subnet B
---------------------------------------------------- 
|    |   |   |   |   |   |   |   |   |    |   |   | 
1-1 1-2 1-3 1-4 1-5 1-6 1-7 1-8 1-9 1-10 2-1 2-2 2-3

With this topology dom0-1 and dom0-2 where seeing the peth0 mac address
in the arp table, so one peth0 could not talk to other across subnet B.
