Strange IP Neighbours problem

Tue Dec 29, 2009 5:19 pm

Hello,

I have a Rb750 connected to 4 ethernets completely unrelated one with the other (in fact, they are 4 ubiquiti bullet devices for ptp networks). It was working fine until a few days ago, when i stopped receiving traffic from the bullets and in ip neighbours, i can see rb750-ether1 advertising in rb750-ether4 (and ether4 advertising in ether1). The bullets are linked to the right network, no loops or anything like that, no packets arrives from rb750 to the bullets, but ether1 receives ether4 and ether4 receives ether1, no bridges nor switch chip enabled or anything like that. happens with routeros 4.3 and 4.4 (i upgraded it just for testing, but no change).

Any ideas?

Thanks
Marcelo
