Hi Rajeev:
To add to Steve's helpful comments, you can use a
combination of bandwidth command under the interface
level along with the auto-cost reference-bandwidth
command to produce the desired ospf cost without
resort to using ip ospf cost command under the
interface. Hence ccbootcamp lab19's intention.
Example from the lab:
int eth 0
bandwidth 200
router ospf 1
auto-cost reference-bandwidth 10
This produces an ip ospf cost of 50 for Ethernet 0
without using the interface command: ip ospf cost 50
BTW, the solution has the wrong command:
ospf auto-cost reference-bandwidth 10
It should be:
auto-cost reference-bandwidth 10
Regards,
Paul Young.
