Route redistribution requires at least one router to do the following:
* Use at least one working physical link with each routing domain.
* A working routing protocol configuration for each routing domain.
* Additional redistribution configuration for each routing protocol, specifically the redistribute command, which tells the routing protocol to take the routes learned by another source of routing information and to then advertise those routes.
The first two steps do not require any new knowledge or commands, but the third step represents the core of the redistribution logic and requires some additional background information.
