What is a recursive static route?
A recursive route net hop and destination address is protected with the help of another route in a routing information base. They are redundant routes and that is the reason for their installation in the RIB.
Most of the people don’t know the recursive static route or got confused in networking that’s why I have gathered a piece of information on it such as what is a recursive static route? How to configure static routes? Those who want to know read the topic to the end
What is a static route?
The static route happens when a manual configuration is used by the router instead of the dynamic configuration routing traffic. Most of the time the static routes are used where the network administrator configures them by entering them into the routing table. But it is not a rule but as the dynamic routing, the static routes are constant even the network changes. Both static and dynamic are use to increase the efficiency of the routing and they also have the backup in case the error occurs. in the subnetwork, static routing is used for the gateway.
Recursive static route
Recursive static routes are covered by RIB the routes are redundant as they are not installed in the RIB. the redistribution is available for a particular route because the recursive allow the needed features during the process of the installation. If the route which is learned is occupied it means the recursive route is removed.
The rules of the recursive roue do not apply to some of the released software. when someone is taking the recursive route, he/she needs to research whether it does affect the other working software or not. Another restriction of the route is if it is occupied for a map then only one route can enter according to virtual routing and forwarding technology, and if the route ma enters the second time the first route-map effect becomes nullify. A recursive static route looks at the routing table at least two times first the destination address is checked and after then the next-hop address is determined.
How to configure the recursive static route?
A recursive route is instead of a link used for pointing the other route in the routing table. Let’s take a look at the example
A static route figure the IP 10.0.0.0 255.0.0.0 Gi0/0
It says that the 10.0.0.0/8 is approachable to Gi0/0 now have other IP address 172.16.1/0 255.255.255.0.10.1.1.1 it describes to reach to 172.16.1.0/24 first you have to go to 10.1.1.1. but what if the connection is not established then what do you do? here you need to look around the routing table and that is what we called a recursive lookup. To find the next-hop address the routing table need to check multiple times.
