Assign Router ID
You can assign a router ID for the OSPFv3 process. Congure an arbitrary value in the IP address format for each router. Each router ID
must be unique. Use the xed router ID for the active OSPFv3 router process. Changing the router ID brings down the existing OSPFv3
adjacency. The new router ID is eective at the next reload.
• Assign the router ID for the OSPFv3 process in ROUTER-OSPFv3 mode.

Congure Stub Areas
The Type 5 LSAs are not ooded into stub areas. The ABR advertises a default route into the stub area to which it is attached. Stub area
routers use the default route to reach external destinations.
1 Enable OSPFv3 routing and enter ROUTER-OSPFv3 mode (1 to 65535).

2 Congure 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 (A.B.C.D) or number (1 to 65535).
• no-summary — (Optional) Enter to prevent an ABR from sending LSAs into the stub area.
