Default route

how default route works

[zanub]

literally gateway of last resort..if router does not have a route to the destination network, then uses default route.

hi,

if router receives a packet,it searches for next hop the packet to be forwared to destination.

if router doesn't finds route to destination in routing table it use default route if it is configured.

There is default route, default gateway, or default network.

Each works off of the "default" premise.

Default literally means last resort or preferred.

When you are routing traffic the administrator tells where to send the traffic.

For instance.

I want traffic coming from 10.1.1.0 255.255.255.0 network to go out a connection at another location, say home office with an IP address of 192.168.1.2 we would put in a static route that looks like this:

ip route 10.1.1.0 255.255.255.0 192.168.1.2

This tells the router to send all traffic from 10.1.1.0 network to our next destination of 192.168.1.2, you could use the exit interface too if you wanted, Serial0/0.

The default route looks like this:

ip route 0.0.0.0 0.0.0.0 192.168.1.2

or

ip route 0.0.0.0 0.0.0.0 Serial0/0 (or any exit interface)

This says, if you don't match anything else use this route to send my traffic.
