I have device "A" on VLAN 30, when I ping a device "B" on VLAN 10, I get response back from device "B" and device "C" both of them on VLAN 10.
Now we suspected some tyep of loop causing Device 'C" also to respond but couldn't figure out the loop. We ended up disabling unicast flooding on VLAN 10, which fixed the issue!! However I still don't understand the underlying issue. Also not sure if disabling unicast flooding would cause some other issue??
Would appreciate any help from Pros.
