Routing - what is redistribution

Redistribution is defined as the transfer of routing information from one source to another. The sources of routing information can include:

• directly connected routes
• static routing configurations
• dynamic routing protocols such as OSPF, EIGRP, RIP, IS-IS, BGP etc…

Note that the first two can only be sources of redistribution. You cannot redistribute routes into directly connected or static routes, it doesn’t make sense. But you can redistribute from directly connected and static routes, into dynamic routing protocols. And of course you can redistribute from one dynamic routing protocol into another.
