Usage
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.
track ipv6 route metric threshold
c e s
Configure object tracking on the threshold of an IPv4 route metric.
Syntax
track object-id ipv6 route ipv6-address/prefix-len metric threshold
To return to the default setting, enter no track object-id.
Parameters
Defaults
None
object-id
Enter the ID number of the tracked object. Range: 1 to 65535.
interface
Enter one of the following values:
• For a 1-Gigabit Ethernet interface, enter gigabitethernet slot-number/
port-number.
• For a Loopback interface, enter loopback number, where number is from 0 to
16383.
• For a Port Channel interface, enter port-channe
l number, where the range is:
C-Series and S-Series: 1 to 128
E-Series: 1 to 255 for TeraScale; 1 to 512 for ExaScale.
• For SONET interfaces, enter the sonet slot-number/port-number.
• For a 10-Gigabit Ethernet interface, enter tengigabitethernet slot-number/
port-number
• For a VLAN interface, enter vlan number, where number is from 1 to 4094.
