Configuring Virtualization

You can configure multiple IS-IS instances in each VDC. You can also create multiple VRFs within each
VDC and use the same or multiple IS-IS instances in each VRF. You assign an IS-IS interface to a VRF.
You must configure a NET for the configured VRF.
Configure all other parameters for an interface after you configure the VRF for an interface. Configuring
Note
a VRF for an interface deletes all the configuration for that interface.
