Any CISCO peeps online?

I probably shouldn't reply to this. I have some experience with CISCO equipment. @Lurick would know more. What do you need?

I has a question good sir.
It was something I noticed when playing in Packet Tracer.
So, with ARP, if the destination IP address is on a different subnet, it will send it to its default gateway, yes?
Now, when the host on the other subnet receives the packet, from my packet tracer model, it looked as though the receiving host sent the reply to its default gateway.
Now, would the reply not be a unicast message direct to the sending host? As its mac address would have been added to the table from when it sent the ARP request?
Basically, I'm confused why the reply seemed to go to the default gateway
-
Ah, that's because ARP is only for the same subnet as the host. If it's on a different subnet then it might ARP for the default gateway if that's not known but after that it will send the packet to the default gateway for routing at that point and the broadcast message would stop at that boundary.
