Re: OSPF route-type per neighbor

Try using multiple ospf process9s on R2 and redistribute from process 1 to
process 2 with metric-type 2 and R3 will see the new metric-type 2, if the
goal is to provide E2 rip routes to R3.

I lab9d this up and it works.

(rip R4)(rip-ospf1 R1)(R2 OSPF19area0' & OSPF29area19)(R3 OSPF2
area 1)
