Hi Andrew,
That is a general redistribution problem. When redistributing IN THE SAME
ROUTER:
OSPF -> EIGRP -> RIP , the OSPF routes will not get into RIP.
Replace those protocols by any other protocol, the rule still applies.
If you want OSPF routes into RIP, you need to distribute OSPF -> RIP
directly.
A different case is R1 running OSPF and EIGRP, and R2 running EIGRP and RIP.
In that case, if in R1 you redistribute OSPF into EIGRP, and in R2 EIGRP ->
RIP, then RIP will get OSPF routes. But not if all redistributions are done
in the same box.
Cheers,
Ato.

Subject: Re: question on EIGRP redistribution
I'm having a problem getting EIGRP to redistribute routes into RIP and
wondering if anyone else has ever seen this or could give me some help
figuring it out.
Here's the deal, I have a router (R3) on MP frame relay interface getting
OSPF routes redistributed into EIGRP.
On this router, the EIGRP topology table lists the redistributed OSPF routes
as 0.0.0.0 (originating from self) and they are external routes
(AD170) where FS (4xxxxxxx/0).
I go to R3 EIGRP neighbors and verify that the external OSPF redistributed
routes are being sent to them. That checks out as expected.
Now I need to redistribute EIGRP into RIP on R3. I do a redistribution as
follows:
Attempt1:
router rip
Version 2
Redistribute eigrp xxx metric 5
Result 1:
Go to other RIP router and the routes are not there... debug ip rip on both
routers with clear ip route * on R3 shows other EIGRP routes being
redistributed, but not the external EIGRP routes.
------
Attempt2:
Router rip
Version 2
Redistribute eigrp xxx route-map eigrptorip
Route-map eigrptorip permit 10
Set metric 5
Result 2:
Go to other RIP router and the routes are not there... debug ip rip on both
routers with clear ip route * on R3 shows other EIGRP routes being
redistributed, but not the external EIGRP routes.
-------------------
Attempt 3:
Router rip
Version 2
Redistribute eigrp xxx rout-map eigrptorip
Route-map eigrptorip permit 10
Set metric 5
Route-map eigrptorip permit 20
Match ip route-type external
Set metric 10
Result:
Go to other RIP router and the routes are not there... debug ip rip on both
routers with clear ip route * on R3 shows other EIGRP routes being
redistributed, but not the external EIGRP routes.
--------
Using attempt 3 setup, I challenge the router by going to an eigrp neighbor
of R3, setting a Lo0 interface with ip 100.100.100.1/24 and under this
routers eigrp process I redistribute connected. Now, I go to R3 and do
clear IP route * and see internal EIGRP routes redistributed with metric 5
as expected but this time.... THE NEW EXTERNAL ROUTE GETS REDISTRIBUTED WITH
A METRIC 10!!!!
What I am seeing is on a single an EIGRP router that GETS redistribution
from one IGP and then attempts to redistribute its EIGRP topology table to
another IGP doesn't forward the external routes.
Can someone confirm what I'm seeing? Or am I experiencing some artifact
inherent to the lab.....
Andy
