The following example configures object tracking on the reachability of an IPv6 route:
Dell(conf)#track 105 ipv6 route 1234::/64 reachability
Dell(conf-track-105)#delay down 5
Dell(conf-track-105)#description Headquarters
Dell(conf-track-105)#end
Dell#show track 105
Track 105

Tracking a Metric Threshold
Use the following commands to configure object tracking on the metric threshold of an IPv4 or IPv6 route.
To remove object tracking, use the
no track object-id
command.
1 (Optional) Reconfigure the default resolution value used by the specified protocol to scale the metric for
IPv4 or IPv6 routes.
CONFIGURATION mode
track resolution {ip route | ipv6 route} {isis resolution-value | ospf
resolution-value }
The range of resolution values is:
• ISIS routes - 1 to 1000. The default is 1 .
• OSPF routes - 1 to 1592. The efault is 1 .
2 Configure object tracking on the metric of an IPv4 or IPv6 route.
CONFIGURATION mode
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.
3 (Optional) Configure the time delay used before communicating a change in the UP and/or DOWN
status of a tracked route.
