*On SwitchA:*
SwitchA receives the request (arp who has) for the IP address of Host B and it checks its MAC table but none found so it will broadcast the request to all ports and changes the Src MAC to that of the switch port that is directly connected to e0 on the router. Switches don't modify frames, they just forward them. So the switch will not modify the src MAC. The frame will be a broadcast as Gert said FF-FF-FF-FF-FF-FF. The router responds with it's MAC and the switch learns what port this MAC sourced from. Or did I misinterpret your text? /Daniel _______________________________________________ cisco-nsp mailing list [email protected] https://puck.nether.net/mailman/listinfo/cisco-nsp archive at http://puck.nether.net/pipermail/cisco-nsp/
