Users Guide

The tracking process uses a protocol-specific resolution value to convert the actual metric in the routing table to a
scaled metric in the range 0 to 255. You can configure the resolution value used to scale route metrics for
supported protocols with the track resolution ip route and track resolution ipv6 route
commands.

Commands
• track ip route metric threshold – configure object tracking on the threshold of an IPv4 route metric.
• track resolution ip route – configure the protocol-specific resolution value used to scale an IPv4 route metric.
track interface ip routing
Configure object tracking on the routing status of an IPv4 Layer 3 interface.
Syntax
track object-id interface interface ip routing
To return to the default setting, use the no track object-id command.
Parameters
object-id Enter the ID number of the tracked object. The range is 1 to 500.
interface Enter one of the following values:
• For a 10-Gigabit Ethernet interface, enter the keyword TenGigabitEthernet then
the slot/port information.
• For a Loopback interface, enter the keyword loopback then a number from 0 to
16383.
• For a port channel interface, enter the keywords port-channel then a number.
• For a tunnel interface, enter the keyword tunnel.
• For a VLAN interface, enter the keyword vlan then a number from 1 to 4094.

Usage Information Use this command to create an object that tracks the routing state of an IPv4 Layer 2 interface:
• The status of the IPv4 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 IPv4 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.
