Hi,

You need a security or data licence to run IP SLA.You can verify with sh licence which one is working on your router.

Hi Lei,

adding to alain....

you need the "DATA" license.  Otherwise you will install routes point to devices that can go down and you will never know it.

I think the (IP sla )command has been updated - rather than 'rtr responder' it's now 'ip sla responder'.

The IP SLA Configuration is different now. I've solved this issue through changing the configuration:

Hope it helps.
