In R4 routing table, R3 ethernet subnet shall be
showing as OSPF External route, it should also be in
the EIGRP topology. But can not be placed in routing
table as it external EIGRP that has higher admin.
distance than OSPF. you can either increase the admin.
distance of R3 ethernet subnet in OSPF or you can
lower its admin. distance in EIGRP. Both ways it will
show up as External EIGRP routre in R4 routing table.
Now as EIGRP knows it so it will in R1 routing table
as External EGRP routeas well.
Hope i did not confuse you..
Thank you,
Aamer
