In the above topology I've configured fairly successfully Redistribution of routing protocols into other protocols domains using route-tagging via route-maps.
- (R1-R5) EIGRP AS 100 can see all OSPF, RIP, and EIGRP AS 200 routes
- (R1 - R2 - R3) OSPF Area 0 can see RIP routes, and routes from both EIGRP AS 100 and AS 200
- (R3 - R4) is able to see EIGRP AS 100 and OSPF routes, but I cannot for the life of me get it to see RIP routes
All I had to do was get RIP and OSPF redistributing, and R5's EIGRP AS 100 got routes no problem and with no further configuration than the OSPF to EIGRP 2-way Redistribution up that way, but for some reason R4 did not get any RIP routes from the OSPF domain, so I set up route-tags and a route-map and Redistributed into each other and still nothing.
I even got so desperate as to try configuring a permit match tag 120 (RIP's tag #) on the OSPF to EIGRP (AS 200) config on R3 and still nothing.
So here is R3's show run, showing the route-maps in place, the RIP2OSPF and OSPF2RIP working fine to get RIP routes up to R5's EIGRP AS:

I have been searching around to see if what I am doing is beyond the limitation of IOS software, please let me know if there is a mis-configuration or if it's just not possible, as I don't want to spin my tires on something that is not fixable - Any more info requested please let me know.
Thanks for any input!!
