The default route in Internet Protocol Version 4 (IPv4) is designated as the zero address, 0.0. 0.0/0 in CIDR notation. Similarly, in IPv6, the default route is specified by ::/0. The subnet mask is specified as /0, which effectively specifies all networks and is the shortest match possible.
What is default route command?
Default route which is also known as the gateway of last resort, is used in forwarding packets whose destination address does not match any route in the routing table. In IPv4 the CIDR notation for a default route is 0.0. 0.0/0 and ::/0 in IPv6.
How do I permanently add a route in Linux?
To configure a permanent static route for an interface, create a file with the following format “/etc/sysconfig/network-scripts/route-<INTERFACE>”. For example, we could create the “/etc/sysconfig/network-scripts/route-eth0” file with the following entries. We can then stop and start the interface as follows.
How does default route work?
A default route is the route that takes effect when no other route is available for an IP destination address. If a packet is received on a routing device, the device first checks to see if the IP destination address is on one of the device’s local subnets.
What does ip route 0.0 0.0 mean?

What is difference between default gateway and default route?
The default-route is used on routers, while the default gateway is used on hosts. As an example, consider a simple home router that connects your home network to the Internet. This router will have two routing rules – one for computers on your internal network, and a default route.
How many default routes can you have?
By default, you can only have one default gateway on a system. The case described would lead to asynchronous routing, whereby the router would reject the packets as appropriate.
Why do we use default route?
The default route is a route that a router uses to forward an incoming packet when no other route is available for that packet in the routing table. Routers use the routing table to make the forwarding decision.

What is default routing example?
A default route defines where packets will be sent if no specific route for the destination network is listed in the routing table. If no default route is set, the router will discard all packets with destination addresses not found its routing table. Consider the following example: We have a network of three routers.
