Re: Redistribution

Hi Anantha,

For any routing protocol to be redistributed into another, the routes
that are considered are the ones in the routing table plus the
connected interfaces on which the redistributed protocol is enabled.
For example in your case, if you are redistributing rip routes into
OSPF, the ospf process on R2 checks the following two things
1) RIP routes in the routing table..kind of running the command show
ip route rip
2) Connected interfaces where the RIP protocol is enabled which means
not all connected interfaces but only the ones which have RIP enabled
on them

While there are a lot of other points of consideration with different
protocols in redistribution , the general rule of redistribution is
the one above.

HTH,
Ravi
