API Guide

Assign Router ID
You can assign a router ID for the OSPFv3 process. Configure an arbitrary value in the IP address format for each router. Each
router ID must be unique. Use the fixed router ID for the active OSPFv3 router process. Changing the router ID brings down the
existing OSPFv3 adjacency. The new router ID becomes effective immediately.
● Assign the router ID for the OSPFv3 process in ROUTER-OSPFv3 mode.

Configure Stub Areas
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.

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.
