IP SLA Tracking Question

[ittechk4u1]

Hello Experts,

i want a route fail-over via three ways...

1. 172.30.64.1 must go via 172.24.18.6 if its available

2. if 1st not available then via 2nd route: 10.15.98.56.....

3. if 1st and 2nd route not available then via 3rd route: 10.15.98.50.

My config:

ip route 172.30.64.1 255.255.255.255 172.24.18.6 track 4
ip route 172.30.64.1 255.255.255.255 10.15.98.56 name Server track 6
ip route 172.30.64.1 255.255.255.255 10.15.98.50 name Server

Is it correct or not? if not then please provide me the correct version!!

Thanks

Hello,

you need to use boolean operators. Post the full config of your router so we can fill in the necessary bits and pieces...

Hello,

I did some testing, and this is what I have come up with (I have changed the SLA numbering for clarity):

track 1 ip sla 1 reachability
!
track 2 ip sla 2 reachability
!
ip sla 1
icmp-echo 172.24.56.2 source-interface GigabitEthernet0/2
threshold 300
timeout 1000
frequency 3
!
ip sla schedule 1 life forever start-time now
!
ip sla 2
icmp-echo 10.13.98.56 source-interface tunnel556
threshold 300
timeout 1000
frequency 3
!
ip sla schedule 2 life forever start-time now
!
ip route 172.31.64.1 255.255.255.255 172.24.56.2 track 1
ip route 172.31.64.1 255.255.255.255 10.13.98.56 10 track 2
ip route 172.31.64.1 255.255.255.255 10.13.98.50 20

is it working or did you test it in your LAB ?

Thanks in advance.

Tested in lab and working. However, check if it works in your live environment as well, to be sure...
