• If the scaled metric for a route entry is less than or equal to the UP threshold,

the state of a route is UP.

• If the scaled metric for a route is greater than or equal to the DOWN threshold

or the route is not entered in the routing table, the state of a route is DOWN.

Configure the UP and DOWN thresholds for each tracked route with the

threshold metric command. The default UP threshold is 254; the default

DOWN threshold is 255. The notification of a change in the state of a tracked

object is sent when a metric value crosses a configured threshold.

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 1-Gigabit Ethernet interface, enter the keyword

GigabitEthernet then the slot/port information.

• 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.

Defaults None
