Task 1
Remove Task 2 configuration from the previous lab.
Task 2
The following prefixes (marked in red rectangle) are advertised by both R3 and R4 (pic. 2). Configure R1 so that it prefers R3 towards these destinations. R4 should only be backup router in case frame-relay circuit towards R3 is down.

Task 2
The following prefixes (marked in red rectangle) are advertised by both R3 and R4 (pic. 2). Configure R1 so that it prefers R3 towards these destinations. R4 should only be backup router in case frame-relay circuit towards R3 is down.
Pic. 2 - Prefixes Advertised by Both R3 and R4.
- If the task did not stipulate that the configuration had to be done on R1, what would be the alternative methods of accomplishing the same goal?

Task 1
Remove Task 2 configuration from the previous lab.
R2 Config:
!
interface fastethernet0/0
no bandwidth 10

Task 2
The following prefixes (marked in red rectangle) are advertised by both R3 and R4 (pic. 2). Configure R1 so that it prefers R3 towards these destinations. R4 should only be backup router in case frame-relay circuit towards R3 is down.

Task 2

Of course, there are usually more than one methods of accomplishing the same goal. If the task did not stipulate that configuration was supposed to be done on R1, we could change the original metric of the prefix on the advertising router(s) using the 'ip ospf cost' command. In case it was not loopback interface, we could also use the bandwidth command to manipulate the original cost calculation.
