when we take a route from one routing protocol and inject that route or distribute it into another routing protocol. Routers by default only advertise and share routing information with other routers running the same protocol and in the same AS. If you have 2 routers and one runs EIGRP and the other runs OSPF and you want them to know about each other’s routes, by default, routers do not share route information because they are not running the same protocol. Here we need redistribution.
In short- Redistribution is the process of exchanging routing information between different routing protocols.
You can use redistribution when using multiple protocols, or migrating to a more advanced routing, and you can use redistribution if you have a mismatch between devices (vendors) or political boundaries.
Note: internal routes are routes advertised within the same protocol.
External routes are routes that get redistributed.
To configure redistribution
The router must be running both protocols
