10SIMULATION -
Lab OSPF -
A sporting goods manufacturer has decided to network three (3) locations to improve efficiency in inventory control. The routers have been named to reflect the location: Boston, Frankfurt, Lancaster. The necessary networking has been completed at each location, and the routers have been configured with single area
OSPF as the routing protocol. The Lancaster router was recently installed but connectivity is not complete because of incomplete routing tables. Identify and correct any problem you see in the configuration.
Note: The OSPF process must be configured to allow interfaces in specific subnets to participate in the routing process.
