5 Change the priority of the interface, which determines the DR for the OSPFv3 broadcast network in INTERFACE mode (0 to 255,
default 1).

Default route
You can generate an external default route and distribute the default information to the OSPFv3 routing domain.
• To generate the default route, use the default-information originate [always] command in ROUTER-OSPFv3 mode.
Congure default route
OS10(config)# router ospfv3 100
OS10(config-router-ospf-100)# default-information originate always

Troubleshoot OSPFv3
You can troubleshoot OSPFv3 operations, as well as check questions for any typical issues that interrupt a process.
• Is OSPFv3 enabled globally?
• Is OSPFv3 enabled on the interface?
• Are adjacencies established correctly?
• Are the interfaces congured for L3 correctly?
• Is the router in the correct area type?
• Are the OSPF routes included in the OSPF database?
• Are the OSPF routes included in the routing table in addition to the OSPF database?
