we have 2 different LANs, a printer and some PCs are connected to LAN 1 via an ethernet cable, and some PCs are connected to LAN 2, also via an ethernet cable. the devices connected to LAN 1 have an IP adress of (192.168.0.x), x), and the devices connected to LAN 2 have IP address in the form of (192.168.1.x).

An administrator configures default gateway configuration manually while configuring the system on the LAN or it can be configured automatically using the DHCP protocol. This packet is encapsulated in Ethernet frame and using the ARP entries on the Host A it forwards the frame to the default gateway on the network.

To do that it builds the Ethernet Frame and puts its MAC address as the Source MAC address (SMAC) and layer 2 broadcast address (ff:ff:ff:ff:ff:ff). PC-2 now creates an Ethernet frame to respond to the ARP. IP address. A switch forwards the broadcast out all the ports in same VLAN (except the port where broadcast was received).
