Configuring OSPF
11-7
2. Issue the area stub command in Router Configuration mode to configure an
OSPF area as a stub area, as shown below:
MOT(config-ospf)#area <area-id> stub
where:
area-id is the OSPF area ID number.
Use the following options to further define your OSPF stub network:
• Use the optional area stub no-summary command in Router Configuration
mode to prevent an area border router (ABR) from sending further Type 3
summary link-state advertisements (LSAs) into the stub area, as shown below:
MOT(config-ospf)#area <area-id> stub no-summary
where:
area-id is the area number.
• Use the area default-cost command in Router Configuration mode to assign a
specific cost to the default summary route sent into the stub area by an area
border router (ABR) only, as shown below:
MOT(config-ospf)#area {<area-id> | <ip-address>} default-cost <cost>
where:
area-id is the OSPF area ID number.
ip-address is the IP address associated with the OSPF area ID.
cost is the outgoing OSPF cost metric for packets sent from the interface,
which is an unsigned 16-bit integer from 0 to 65535.
Note: If there is more than one router within a stub area, ensure that the area
that you are creating as a stub area is defined as a stub area on each of
these routers.
