Hi Guys,
i have created topology where i want to Track 8.8.8.8 IP.
if first path with deafult route goes down then it should take another deafult route which is having higher AD.
Please find attached file and below config.
R2:
ip sla 1
tcp-connect 8.8.8.8 5000
ip sla schedule 1 life forever start-time now
track 10 ip route 8.8.8.8 255.255.255.255 reachability
ip route 0.0.0.0 0.0.0.0 20.20.20.1 track 10
ip route 0.0.0.0 0.0.0.0 30.30.30.1 10
---------------------------------
As per current config, i am able to ping 8.8.8.8 ip which is configured at R4 from R2.
R2# traceroute 8.8.8.8
Type escape sequence to abort.
Tracing the route to 8.8.8.8
1 20.20.20.1 52 msec 56 msec 52 msec
2 10.10.10.1 100 msec 100 msec 52 msec
3 40.40.40.2 92 msec 56 msec 84 msec
Core_Switch#
R2# traceroute 8.8.8.8
Type escape sequence to abort.
Tracing the route to 8.8.8.8
1 30.30.30.1 76 msec 80 msec 84 msec
2 40.40.40.2 128 msec 80 msec 104 msec
My requirement is to go from 20.20.20.1 and if any failure on this path then need to shift on 30.30.30.1 with IP SLA tracking in TCP-connect, Can anyone please help into this?

Hello Noovi,
with your current configuration you are not tracking the IP SLA
try the following
track 11 ip sla 1
if this command is accepted then you can modify the primary default route to use track 11 instead of track 10.
(you need to remove it and add again with final track 11 parameter)
Hope to help

Hello Noovi,
your device does not support enhanced object tracking for IP SLA
the correct command syntax should be
track 11 ip sla 1 state
see this link for C4500 catalyst
I don't know if this a platform limitation or a question of licensing / image type.
We should look in Cisco feature navigator to see if the feature is supported on C3850.
Edit1:
feature navigator link
https://cfn.cloudapps.cisco.com/ITDIT/CFN/jsp/index.jsp
edit2:
searching by feature using feature "FHRP - Enhanced Object Tracking of IP SLAs" I find IOS XE images for ASR 1000 or catalyst 4500 no catalyst 3850 up to now.
Hope to help
Giuseppe
