5.) when i am traceroute from R6 to R1 for 200.x.x.x it is taking the path
as follow:
R6 --> R4 --> R2 --> R1-->200.x.x.x
>On R6 show ip ospf database and please post the results and post "show ip
ospf database summary 200.x.x.x 255.x.x.x"
>And on R6 please post show ip route. Do you have anything else running?
Eigrp? Bgp?
i am expecting the path as below , thinking it is the best path to reach
destination.
R6 --> R4 --> R3 --> R1-->200.x.x.x
>Yes Between R6 (in Area 2) and R1 (in Area 1) traffic must route through
area 0, so it should go from R6, R4, <over area 0> R3, R1
