Hi ,
Router id is the way a router will know about the originator of the route,
when you redistribute from OSPF into EIGRP, the routes will be treated as
external on the redistributing router, you could check it with show ip eigrp
topology X.X.X.X and it will show the RID of R2 as the originator, when R1
receives this route, he finds that RID of the originator is the same as its
own and ignores the route, this can be seen with show ip eigrp events
command I think.
Solution : change RID of R1,
router eigrp AS
eigrp router-id Y.Y.Y.Y
or create a loopback with another higher IP address.
Hope it helps
Shanky
