Well, since you do not enable RIP on that interface, it is not included in
the RIP process.
You do a redistribution, so it's kind of external.
As I said below, If you then redistribute RIP into EIGRP (on the same
router), this loopback will not being redistributed into EIGRP. You would
also have to do a redistribute connected on EIGRP and include this
interface.
Someone else in a forum explained me this once with the words: "It has to do
with who "owns" the route. It's a secondary check to prevent loops in
redistribution on the local device"

Roger

Roger,
Yes my question is about this LoopBack interface. As this interface is
redistributed into RIP, Do we have to count this loopback as a part of RIP,
and we must redistribute it as a connected into EIGRP?

Yes, you have to, because you only say to redistribute RIP into EIGRP but
this Loopback is a connected interface.
So then, if you do also a redistribute connected into eigrp and specify a
route map, you would also have to add the eth0/0 RIP interface into the
route-map, because this is also a connected interface.
Lab it up, you will see

Roger

Hello
R1 has 2 Ethernet InterfacesE0/0 and E0/1 and a LoopBack 0
R1 is running RIP on E0/0
R1 is running EIGRP on E0/1
Task is asking to advertise Loopback into the RIP without "network" command.
So we do redistribution with a route-map to match the loopback interface.
Next
Task is asking redistribute RIP into EIGRP.
For this task I use "redistribute rip metric 1 1 1 1 1"
the router performs a "show ip route rip" and finds the RIP routes and
redistributes them into EIGRP
the router finds the interfaces which are running RIP (in this case
E0/0), and redistributes it into EIGRP
now Do we need to manually redistribute the Loopback interface which is
already redistributed into RIP in previous question, into the EIGRP?
Thanks
Reza
