Chapter 7      Configuring OSPFv3
Configuring Advanced OSPFv3
To restart an OSPFv3 instance and remove all associated neighbors, use the following command:
Configuring OSPFv3 with Virtualization
You can configure multiple OSPFv3 instances in each VDC. You can also create multiple VRFs within 
each VDC and use the same or multiple OSPFv3 instances in each VRF. You assign an OSPFv3 interface 
to a VRF.
Note Configure all other parameters for an interface after you configure the VRF for an interface. Configuring 
a VRF for an interface deletes all the configuration for that interface.
BEFORE YOU BEGIN 
Create the VDCs.
Ensure that you have enabled the OSPF feature (see the “Enabling the OSPFv3 Feature” section on 
page 7-13).
Ensure that you are in the correct VDC (or use the switchto vdc command).
