Configuration of Static and Default Route

Static Routing/ Route

Static Routing is a process in which routing is performed with the help of manually configured routes in router. In static routing all the remote networks are configured on routers connected in network.

Command to Configure Static Route of networks in router
ip route <other network address> <subnet mask> <source exit interface number/ destination entry interface IP Address>

Default Route

Default Route is a setting which is used to define the rules of packet forwarding which are to be used when there is no specific route is determined in network to forward the packet for the given IP (Internet Protocol) address of destination. All packets having destination addresses which are not in routing table are sent through Default Route from one network to other network.

Command to Configure Default Route of networks in router
ip route 0.0.0.0 0.0.0.0 <source exit interface number/ destination entry interface IP Address>
