Prerequisites: CCNP level skills.
Note!
Use OSPF point-to-multipoint on the Frame-Relay connections (configuration and topology from Lab20).

Task 2
Manipulate the OSPF bandwidth so R1 prefers R3 towards 10.1.23.0/24.
Lab Solution
Task 1
On R1 check the paths towards 10.1.23.0/24.
Pic. 2 - R1's Routing Table.
Note! R2 is the DR on 10.1.23.0 segment. Both R2 and R3 are advertising the subnet.
Note!
Both R2 and R3 calculate the cost of 10.1.23.0/24 based on the bandwidth (100Mbps). The cost is: 1.
Task 2
Manipulate the OSPF bandwidth so R1 prefers R3 towards 10.1.23.0/24.
R2 Configuration:
!
interface FastEthernet1/0
bandwidth 10000
ip address 10.1.23.2 255.255.255.0
bandwidth 10000
ip address 10.1.23.2 255.255.255.0
!
Verification:
Pic. 3 - R2's cost is changed from 1 to 10.
Pic. 4. - R1's Routing Table.
