R2 has two connections to R4, R2/R4 is running OSPF on one and RIP on the other.
R4 gets the same routes from R2 as both OSPF and RIP, will prefer
the routes from OSPF because of AD 110 then redistribute these to EIGRP.
Since R4 does not have them in the routing table via RIP it does not
redistribute them to R5, so no full reachability.
R1 e0/0 is attached to R2 e0/0 running rip
R2 s0/0 is attached to R4 s0/0 redistributing rip and ospf
R2 s0/1 is attached to R4 s0/1 running rip
R4 e0/0 is attached to R6 e0/0 redistributing eigrp and ospf
R4 e0/1 is attached to R5 e0/0 running rip

It's also unclear to me. Does R2 only have a connection to R1 and R4 and
not to R6 or R5? If so then there is no problem since R4 will always show
R2 as the next hop to get to those R1 RIP originated routes.
