Tracking Route Reachability
To configure object tracking on the reachability of an IPv4 or IPv6 route, use the following commands. To
remove object tracking, enter the
no track object-id command.
Command Example:
track ip route reachability
FTOS(conf)#track 104 ip route 10.0.0.0/8 reachability
FTOS(conf-track-104)#delay up 20 down 10
FTOS(conf-track-104)#end
FTOS#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:
FTOS#configure
FTOS(conf)#track 4 ip route 3.1.1.0/24 reachability vrf vrf1
Step Task Command Syntax Command Mode
1 Configure object
tracking on the
reachability of an IPv4
or IPv6 route.
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.
CONFIGURATION
2 (Optional) Configure
the time delay used
before communicating
a change in the status
of a tracked route.
delay {[up seconds] [down seconds]}
Valid delay times are from 0 to 180 seconds. Default: 0.
OBJECT TRACKING
3 (Optional) Identify the
tracked object with a
text description.
description text
The text string can be up to 80 characters.
