we are having multiple VLANs in our infrastructure. for all the VLANs except 1 vlan when we ping the brodcast IP of that vlan pool, we get a reply from the gateway ip of the VLAN. But only for 1 vlan we are getting very wierd behaviour. for this VLAN we get a reply from some random machines from the LAN. We are unable to trace this issue as why any machines in LAN are replying when we ping brodcast IP of that LAN. Can any 1 please suggest possible cause ... Thanks in advance.
