IP SLA Probe Failing

[ahalwani]

Hi,

I have a router configured with ip sla icmp echo to track some ip addresses in order to make some routing decisions.

However, although I can ping the IP addresses just fine from the router with the correct source interface, their corresponding ip sla probes fails sometimes. At first usually all seems to be working fine then after some time some ip addresses fails and stay that way and usually only way i can fix this is to track new IP addresses.

My router is a C2811 with Advanced IP Services 12.4(22)T.

Anyone faced a similar problem before.

Thanks,

What error do you see when you run "show ip sla stat" for these collectors?  When they are failing can you manually ping the same addresses from the device?  If you enable "debug ip sla error" and "debug ip sla trace" what messages do you see?
