Dell SmartFabric OS10 User Guide Release 10.5.3

Type 5 LSAs are not flooded into stub areas. The ABR advertises a default route into the stub area where it is attached. Stub area routers use the default route to reach external destinations.

1. Enable OSPFv3 routing and enter ROUTER-OSPFv3 mode, from 1 to 65535.

   router ospfv3 instance number

2. Configure an area as a stub area in ROUTER-OSPFv3 mode.

   area area-id stub [no-summary]

   • area-id — Enter the OSPFv3 area ID as an IP address in A.B.C.D format or number, from 1 to 65535.
   • no-summary — (Optional) Enter to prevent an ABR from sending summary LSAs into the stub area.
