Assume that networks 172.15.10.0/24 and 172.15.11.0/24 are connected through a router with interfaces 172.15.10.254 (MAC3) and 172.15.11.253 (MAC4).

If host A sends a packet through its network interface 172.15.10.1 (MAC1) to interface 172.15.11.1 (MAC2), what's the MAC and IP source and destination addresses of the MAC/IP packets in the two networks?


Does the IP/MAC addresses of the initial request correspond to the router or the destination machine?

MAC addresses are confined to the local network because routers strip the frame off a packet to route the packet to a new network interface. The router then builds a new frame for the protocol on the new interface (remember that not all data-link protocols use MAC addressing).

The IP addresses will remain on the packet from source to destination.
