Hi expert,

pls respond

[Dmytro Skotnikov]

Hello subhojit halder,

Please, collect the following outputs:

# show ip sla monitor configuration 10

# show ip route vrf CHECK 10.191.193.28

And verify correct behavior of regular ping:

# ping vrf CHECK 10.191.193.28 source 10.191.193.16

Another question is you are tracking under vrf CHECK, but setup static route for vrf LEGACYMAN, is it an expected design?

Thank you

I think I see what the problem is. Sorry to solve it after 4 years. But do let me know if I got it or not . I will really appreciate it.

In your case your saying:

ip sla 10
icmp-echo 10.191.193.28 source-ip 10.191.193.16
timeout 4000
vrf CHECK

frequency 5

So here you are saying ''timeout if u dont get a response within 4 seconds and you do that test every 5 seconds . So you're timing out  before u send out the echo/ping requests. So you're timeout has to be more then the frequency by my understanding. Let me know how you resolved it.
