Static Routing Benefits: It increase security because the admin can choose to allow routing access to certain networks only. It does not increase the CPU overhead. It is beneficial for small networks. Limitations: It is difficult to implement in big network because every organization need to keep the accurate map of the network. If you do not have the map then the results will be worse. All the configuration need to be done manually & if need to make any change that have to be done manually which in turn increase the manual overhead. Difficult to configure in big network /  internetwork.
 * It is done by administrator manually. In this way, Administrator can keep the full control of domain. It has many benefits & limitations which are given below:

How to add the static route entries : The command syntax is written below IP Route: This command used to create the static route. Destination N/w: The network which we need to place in the routing table. Mask: The mask being used on the network. Next-hop-address: The address of the next router, which will receive the traffic & forward it ahead. Exit Interface: The outgoing interface of the device, which is used to send the traffic out towards destination.
 * 1) IP route < Mask >< Next-hop address | exit  interface >   permanent.

Sample of configuration:
 * 1) IP   Route      10.0.0.0      255.0.0.0     50.0.0.10
 * 2) IP   Route      10.0.0.0      255.0.0.0     serial     0/1/0

Administrative Distance: It defines the trustworthiness among the Routing Protocols. Lower AD value protocol is more preferable. For Example: If two protocols are running on the same router, then the protocol with the lower AD will be preferred.

Default Routing: Normally, if a specific route to a particular network does not exist, a router will drop all traffic destined to that network. A default route, or gateway of last resort, allows traffic to be forwarded, even without a specific route to a particular network. The default route is identified by all zeros in both the network and subnet mask (0.0.0.0 0.0.0.0). It is the least specific route possible, and thus will only be used if a more specific route does not exist (hence “gateway of last resort”).
