OSPFv3 Routing
This section gives an overview of Open Shortest Path First Version 3 (OPSFv3) routing and its implementation in the
system. It also describes how to enable the base OSPFv3 functionality and lists the commands that are available for
more complex configurations.

OSPFv3 Overview
Much of OSPF version 3 is the same as OSPF version 2. OSPFv3 expands on OSPF version 2 to provide support for
IPv6 routing prefixes and the larger size of IPv6 addresses. OSPFv3 dynamically learns and advertises (redistributes)

In OSPFv3, a routing process does not need to be explicitly created. Enabling OSPFv3 on an interface will cause a

routing process and its associated configuration to be created.
Basic OSPFv3 Configuration
This section describes how to implement basic OSPF routing.
Enabling OSPFv3 Routing For a Specific Context
Use the following configuration example to enable OSPF Routing for a specific context:
config
context context_name
router ospfv3
end
Notes:
Save your configuration as described in the Verifying and Saving Your Configuration chapter.
Enabling OSPFv6 Over a Specific Interface
After you enable OSPFv3 specify the area in which it will run. Use the following command to enable OSPFv3:
area { area_id | area_ip_address } [ default-cost dflt-cost ] [ stub stub-area ]
[ virtual-link vl-neighbor-ipv4address ]
[ virtual-link vl-neighbor-ipv4address ]
Important:
The default cost for OSPFv3 on the system is 10. To change the cost, refer to the ipv6 ospf cost
command in the Ethernet Interface Configuration Mode Commands chapter of the Command Line Interface Reference.
Notes:
Save your configuration as described in the Verifying and Saving Your Configuration chapter.
