Prerequisites: CCNP level skills.
Note!
Use OSPF point-to-multipoint on the Frame-Relay connections (configuration and topology from Lab20).
Use OSPF point-to-multipoint on the Frame-Relay connections (configuration and topology from Lab20).
Topology
Pic. 1 - OSPF Topology.
Task 1
Task 2
Manipulate the OSPF cost so R1 prefers R2 towards 10.1.23.0/24. Do not use 'ip ospf cost' or 'bandwidth' commands.
Lab Solution
Task 1
On R1 check the paths towards 10.1.23.0/24.

Manipulate the OSPF cost so R1 prefers R2 towards 10.1.23.0/24. Do not use 'ip ospf cost' or 'bandwidth' commands.
R1 Configuration:
!
router ospf 1
router-id 1.1.1.1
log-adjacency-changes
network 10.1.1.1 0.0.0.0 area 0
network 172.16.101.1 0.0.0.0 area 0
neighbor 10.1.1.3 cost 66
router-id 1.1.1.1
log-adjacency-changes
network 10.1.1.1 0.0.0.0 area 0
network 172.16.101.1 0.0.0.0 area 0
neighbor 10.1.1.3 cost 66

Note!
The 'neighbor address cost' command can only be used with OSPF point-to-multipoint mode.
