2. Enter CONFIGURATION mode. EXEC Privilege mode configure
3. Enter ROUTER OSPF mode. CONFIGURATION mode router ospf process-id Process ID is the ID assigned when configuring OSPFv2 globally.
4. Configure the area as a stub area. CONFIG-ROUTER-OSPF-id mode area area-id stub [no-summary] Use the keywords no-summary to prevent transmission into the area of summary ASBR LSAs. Area ID is the number or IP address assigned when creating the area.
