Subject: RE: ARP Broadcast
When working with Lay3, it must be mapped to something
that is Lay2, MAC,DCLI, VPI/VCI... so that the system
knows how to handle it. Dynamically, this is sloved by
ARP. When you want to ping 1.1.1.1, your PC/router
needs to know the MAC address/DLCI number of 1.1.1.1
in order to talk to it over LAN or FR, but it does not
know it, how can we let it know dynamically without a
kind of broadcast? when you say unicast, do you mean
the MAC address of the destination which your machine
does not know yet?
When it is point-to-point, there is no need to have
the concepts of broadcast and unicast, because there
are only two nodes, you just send everything to a
specific address, and program your software or
hardware to always listen to that address when they
are in point-to-point mode.
