I can't find the doc anywhere to answer my question so I'm am hoping someone can help me out ;)
I have a 3750 set as a gateway router on one of the VLANs. From a host somewhere out there on the VLAN I send an ARP request for the gateway address which is the 3750. The ARP is received by the 3750 as a tagged packet with pbit=0. The 3750 sends an ARP reply as expected but the pbit=7.
My question is why is the ARP reply marked with pbit=7? I have my hunches as to why but I usually get into trouble when I assume.
I'd really appreciate the feedback.
