IP Route 0.0. 0.0 is used as another way to set the gateway of last resort on a router. Does not allow Routing of transitive traffic i.e. cannot route packets from downstream networks to Upstream networks. The device configured with “IP Default-Gateway” can only route its packets to other networks.

What is the default route IP address?

The default route in IPv4 is designated as 0.0. 0.0/0 or simply 0/0. Similarly, in IPv6, the default route is specified as ::/0. The subnet mask /0 specifies all networks, and is the shortest match possible.
