The problem:
• R1 is configured with redundant bidirectional connection between R3 and R4's Lo0. Its like multihome internet connection setup.
• R2 is the preferred path between R3 and R4.
• R1 is using NAT to allow connectivity, exposing R3 as 4.3.12.3 and 4.3.15.3.
• R3 can't reach R4 and vice versa.
• Fix the problem without changing configuration on R2,R4 and R5. Keep the solution redundant.
• Use telnet to check connectivity. You are allowed to configure one static route.

The problem:

R6 was configured to summarize R3's Lo30,Lo31,Lo32 and Lo33, so R4 would see only one summarized route for them.
However, R4 still sees all the routes.
Fix the problem while, making sure R6 sees all R3's routes.
