Configuring an IP Address Pool for Clustering (OSPFv2 and OSPFv3) You can assign a range of IPv4 addresses for the router ID cluster pool if you are using Layer 3 clustering. The key argument specifies the number used in the calculation of the message digest. If the no interface_name argument is specified, all of the interfaces in the OSPFv3 process process_id are made passive.
