track ip route reachability
Figure 31-6. Command Example:
track ipv6 route reachability
Tracking a Metric Threshold
To configure object tracking on the metric threshold of an IPv4 or IPv6 route, use the following
commands. To remove object tracking, enter the
no track object-id
command.
Step Task Command Syntax Command Mode
1 (Optional) Reconfigure the
default resolution value used by
the specified protocol to scale the
metric for IPv4 or IPv6 routes.
track resolution
{
ip route
|
ipv6 route}
{isis
resolution-value
| ospf
resolution-value
}
Range of resolution values:
ISIS routes - 1 to 1000. Default: 1.
OSPF routes - 1 to 1592. Default: 1.
CONFIGURATION
2 Configure object tracking on the
metric of an IPv4 or IPv6 route.
track
object-id
{
ip route
ip-address/prefix-len |
ipv6 route
ipv6-address/prefix-len }
metric threshold
[
vrf
vrf-name ]
Valid object IDs are from 1 to 65535.
Enter an IPv4 address in dotted decimal format.Valid
IPv4 prefix lengths are from /0 to /32.
Enter an IPv6 address in X:X:X:X::X format. Valid
IPv6 prefix lengths are from /0 to /128.
(Optional)
E-Series only : For an IPv4 route, you can
enter a VRF name.
