For ISIS, you can set the resolution in the range from 1 to 1000, where the default is 10.
For OSPF, you can set the resolution in the range from 1 to 1592, where the default is 1.
The resolution value used to map static routes is not configurable. By default, Dell EMC Networking OS assigns a metric
of 0 to static routes.
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 500.
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 objects status.
EXEC Privilege mode
show track object-id
The following example configures object tracking on the reachability of an IPv4 route:
DellEMC(conf)#track 104 ip route 10.0.0.0/8 reachability
DellEMC(conf-track-104)#delay up 20 down 10
DellEMC(conf-track-104)#end
DellEMC#show track 104
Track 104
IP route 10.0.0.0/8 reachability
Reachability is Down (route not in route table)
2 changes, last change 00:02:49
Tracked by:
DellEMC#configure
DellEMC(conf)#track 4 ip route 3.1.1.0/24 reachability vrf
vrf1
The following example configures object tracking on the reachability of an IPv6 route:
DellEMC(conf)#track 105 ipv6 route 1234::/64 reachability
DellEMC(conf-track-105)#delay down 5
DellEMC(conf-track-105)#description Headquarters
DellEMC(conf-track-105)#end
DellEMC#show track 105
