it is where the router sends all packets with destination of which it has knowledge.
When you have routing enabled then you need default route (also calleddefault network or Gateway of Last Resort). You do not need default routeif you don't use routing. For example if you just have one router in your network there is no need for default route. When you have more than one router in a network you need default route.Note: If you connect to WAN (Internet) you need default route. The default route allows connection with Internet. If you are not using WAN and have one router than there is not need for default route but in these days everyone connects to the Internet so most likely your router has default route. When using router to connect to the Internet using DHCP this happens automatically so there will no need to configure default route manually. If you need to manually set default route then use the commands IP default-network or IP route 0.0.0.0 0.0.0.0 .More info can be found at Cisco's site - see the related link below.

--> If the destination network is directly connected, the router forwards the packet to the destination host. --> If no route exists for the destination network and a default route is present, the packet is forwarded to the next-hop router. --> If the originating host has a default gateway configured, the packet for a remote network can be forwarded using that route.

ip default gateway
A host uses a default route to transfer data to a host outside the local network when no other route to the destination exists. You may configure the gateway of last resort to achieve this functionality especially if there is a need to route packets outside the LAN. The way to configure a default route to a Cisco Layer 3 device is as follows: Router(config)# ip route <network-address> <subnet-mask> <next-hop-address> Example: Router(config)# ip route 0.0.0.0 0.0.0.0 172.18.3.1
The administrative distance of a default route is typically 1. This means that it is considered the most reliable and preferred route for forwarding traffic when no other more specific route is available in the routing table.
default
A default route is considered a gateway of last resort; meaning all ip packets that don't have a match in the routing table of a router will be forwarded to the default route. An ultimate route is a route in the routing table of a router that indicates both the next hop ip address and the exit interface.
