I have just tried this. Initally I had the same as you. R11 have learnt the
routes through EIGRP before OSPF had a full adjacency with R10. Once I done
a clear ip route * everything is as you would expect. If I shut down the
Ethernet interface of R11 and bring it back up the same thing happens, until
I do a clear ip route * the EIGRP routes are installed into the routing
table.
Seems like a but to me unless somebody can explain this? I am running
12.1(10a) on R11.

Subject: Are EIGRP external routes preferable than OSPF ext ??
Hi I have simple setup:
R9:(e0) (IGRP) ------(e0/0)R10(e1/0) (IGRP, EIGRP, OSPF)----(e0)R11 (EIGRP,
OSPF)
There is redistr between IGRP,OSPF and EIGRP on R10.
So, routes from R9 are redist to EIGRP and to OSPF on R10 and received on
R11 (via both ospf and eigrp)
Somehow I see R9 loopbacks routes on R11 as learned via EIGRP (external),
but OSPF...
D EX has distance 170, OSPF 110, but there are no ospf routes in routing
table on R11.
However, they are in database as external. When I stop EIGRP on R11, I can
see OSPF E2 routes there.
If I stop ospf running on e0/0 (R10) - everything is OK - R11 see all
external routes as O E2.
Why ??
