Hi
Please clarify a basic doubt. In a multilayer box, when a packet (say ethernet) comes, on what basis the box decides to route (L3) or switch (L2)
Thanks

Ask a écrit :
It routes when the destination MAC address is the router address.
Furthermore, if it owns either A) both the receiving and destination network, or B) the receiving network and a next-hop network towards the destination, it will route the packet. If it does not have a layer 3 interface in the networks, or the receiving and destination network are one and the same, the switch will switch the packet. It should also be said that I am assuming we are ignoring CEF and other technologies, and assuming that this is the first packet for this source/destination since age-outs and other things.
