Information
Use this command to create an object that tracks the routing state of an IPv6 Layer 3 interface:
• The status of the IPv6 interface is UP only if the Layer 2 status of the interface is UP and the
interface has a valid IP address.
• The Layer 3 status of an IPv6 interface goes DOWN when its Layer 2 status goes down (for a
Layer 3 VLAN, all VLAN ports must be down) or the IP address is removed from the routing
table.
