He're you'll be setting some metrics and observing the effects.
Examine link costs that your router is advertising out
Use the show ospf interface detail. command
Observe the Costs of your Ethernet interface and loopback interface
Use the show ospf database advertising-router self detail command and match up the link costs with what the show ospf interface detail command reported
Configure a bandwidth statement on one of your Ethernet interfaces for a bandwidth between 10 Kbps and 50 Mbps and observe what happens to the link cost
Change the bandwidth statement to 155 Mbps and observe what happens to the link costs
Change the bandwidth statement to 10 Gbps and observe what happens to the link costs
Change your reference bandwidth to 25 Gbps and observe what happens to the link costs
Configure a cost of 1234 on the interface with the bandwidth statement and observe what happens to the link costs
Set the overload condition on your router and observe what happens to the link costs
Examine the costs your router is advertising out by looking at the LSDB
Check the route
Clear the overload condition and check that things are back to normal
Wait until all routers are configured up to this point before proceeding
Set the metrics on the links in accordance with the diagram below
Check traffic flow on the following links (J2300-1, J2300-2), (J2300-2,J2300-3), (J2300-4,J2300-5) by perform traceroutes between loopback addresses and confirm what happens when metrics are not necessarily equal
Lab OSPF Metrics
After all the traceroutes are finished between router pairs above
Change all of the interface metrics to a common value of 5 on all Ethernet links
