Confirming OSPFv3 Configuration Parameters

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 ]
Important
Notes:
• Save your configuration as described in the Verifying and Saving Your Configuration chapter.

Redistributing Routes Into OSPFv3 (Optional)

Redistributing routes into OSPFv3 means any routes from another protocol that meet specified a specified
criterion, such as route type, metric, or rule within a route-map, are redistributed using the OSPFv3 protocol
to all OSPF areas. This is an optional configuration.

• Save your configuration as described in the Verifying and Saving Your Configuration chapter.
Confirming OSPFv3 Configuration Parameters
To confirm the OSPF router configuration, use the following command and look for the section labeled router
ipv6 ospf in the screen output:
show config context ctxt_name [ verbose ]

Equal Cost Multiple Path (ECMP)

The system supports ECMP for routing protocols. ECMP distributes traffic across multiple routes that have
the same cost to lessen the burden on any one route.
ECMP can be used in conjunction with most routing protocols, since it is a per-hop decision that is limited
to a single router. It potentially offers substantial increases in bandwidth by load-balancing traffic over multiple
paths

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.
