Hi all
Proxy ARP is the process where a router responds to an ARP request with it's
MAC address. By default, Proxy ARP is enabled on Cisco routers.
Let's consider the following topology and all the three devices are in
10.20.30.0/24 subnet.
Host A -------------------------
I -------------------------- Router
Host B ------------------------
Now, if Host A sends an ARP request to Host B. Both Host B and the router
(Proxy ARP) should send an ARP response, isn't it? But in reality this
doesn't happen. Is this because the router doesn't send Proxy ARPs, if the
routes are directly connected?
With regards
Kings
