Hi Ronnie:
Mapping R4 is surely a work around. But, ospf doesn't have next-hop
attribute and R3 seeing R4 as next-hop is wrong/not-expected (can some one
comment?) , desirable in many situations though.
Could you verify these: 1)in R3 are you seeing the RIP originated routes as
ospf-external routes?in R4, sho ip route 2) Is R4 ospf-peering with R7?(sho
ip os ne''in R4) 3)can you also give the ios image on R7?
If i get time i will work on my routers and give more info.
regards,
gopal
