DETAILED STEPS
Use the no feature ospfv3 command to disable the OSPFv3 feature and remove all associated
configuration.
Creating an OSPFv3 Instance
The first step in configuring OSPFv3 is to create an instance or OSPFv3 instance. You assign a unique
instance tag for this OSPFv3 instance. The instance tag can be any string. For each OSPFv3 instance,
you can also configure the following optional parameters:
• Router ID—Configures the router ID for this OSPFv3 instance. If you do not use this parameter, the
router ID selection algorithm is used. See the “Router IDs” section on page 1-5.
• Administrative distance—Rates the trustworthiness of a routing information source. See the
“Administrative Distance” section on page 1-7.
• Log adjacency changes—Creates a system message whenever an OSPFv3 neighbor changes its
state.
• Maximum paths—Sets the maximum number of equal paths that OSPFv3 installs in the route table
for a particular destination. Use this parameter for load balancing between multiple paths.
