the router will enqueue the packet that is sent to the destination 192.168.1.4.and then that packet is sent on transmission media(cable).it checks every ip address that is holding the ip same as the destination ,if it reaches there then it deleiver it on that machine.
It will forward the packet to the default gateway.
decapsulates the Layer 3 packet by stripping off the Layer 2 frame header uses the destination IP Address in the IP header to look up the next-hop address in the routing table encapsulates the Layer 3 packet into the new Layer 2 frame and forwards it out the exit interface
Answering "If a router recieves a packet that is does not know how to foward what type of route must be configured on the router to prevent the router from dropping it?"
** the first path that the router learned.
nothing.
packet-filtering
a packet filtering fire wall
1.The router will discard the packet. 2.The router will send a time exceeded message to the source host.
The default route must be configured such as: Ip route 0.0.0.0 0.0.0.0 serial 0/0 etc.
Router uses IP address of destination node to do the direct packet switching..while bridge & switch uses the MAC address to packet forwarding.
The router only needs to know the next-hop address; in other words, it sends the data to the next router; this next router then takes its own decision.Each router maintains a routing table, with information about where to send IP packets. The information is stored on a per-network basis. When the router receives an IP packet, it consults the routing table, to see what is the next-hop address, and through which interface it must send the packet.The router only needs to know the next-hop address; in other words, it sends the data to the next router; this next router then takes its own decision.Each router maintains a routing table, with information about where to send IP packets.

The router will use gateway of last resort IP address to forward packets destined to 192.168.254.254.
