The problem:
- R3 is the DHCP server on V100.
- R1 was configured to be a backup for the DHCP server on R3. R1 is using object tracking and EEM to do so.
- However, the solution is not working and even if it was its too slow and unreliable. Fix the problems.
- Do not use BFD, its not working on dynamips :)

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.
