• The resolution value used to map RIP routes is not configurable. The RIP hop-count is
automatically multiplied by 16 to scale it. For example, a RIP metric of 16 (unreachable) scales to
256, which considers a route to be DOWN.
Tracking Route Reachability
Use the following commands to configure object tracking on the reachability of an IPv4 or IPv6 route.
To remove object tracking, use the
no track object-id
command.
1 Configure object tracking on the reachability of an IPv4 or IPv6 route.
CONFIGURATION mode
track object-id {ip route ip-address/prefix-len | ipv6 route ipv6-address/
prefix-len } reachability [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 to specify the virtual routing table
to which the tracked route belongs.
2 (Optional) Configure the time delay used before communicating a change in the status of a tracked
route.
OBJECT TRACKING mode
delay {[up seconds ] [down seconds ]}
Valid delay times are from 0 to 180 seconds.
The default is 0 .
3 (Optional) Identify the tracked object with a text description.
OBJECT TRACKING mode
description text
The text string can be up to 80 characters.
4 (Optional) Display the tracking configuration and the tracked object’s status.
EXEC Privilege mode
show track object-id
Examples of IPv4 and IPv6 Tracking Route Reachability
Examples of IPv4 and IPv6 Tracking Route Reachability
The following example configures object tracking on the reachability of an IPv4 route:
Dell(conf)#track 104 ip route 10.0.0.0/8 reachability
Dell(conf-track-104)#delay up 20 down 10
Dell(conf-track-104)#end
Dell#show track 104
Track 104
IP route 10.0.0.0/8 reachability
