Hello,
I have a router with IP SLA configured. Configuration is as follows :
ip sla 2
http get http://www.cisco.com source-ip A.A.A.A name-server B.B.B.B
tag WEB
ip sla schedule 2 life forever start-time now
A.A.A.A is a public IP address configured on g0/1 interface (which is up/up) and B.B.B.B a valid DNS server.
Ping ok to the DNS server with A.A.A.A as the source address.
Instead of using the source-ip A.A.A.A, the router uses another one (C.C.C.C configured on the g0/0 interface, private IP address) even if it's not configured on the IP SLA parameters.
Here is the debug :
Jun 1 16:06:53 MEZ: IPSLA-INFRA_TRACE:OPER:2 slaSchedulerEventWakeup
Jun 1 16:06:53 MEZ: IPSLA-INFRA_TRACE:OPER:2 Starting an operation

I tried to deactivate and reactivate IP SLA parameters but without success.
Thanks for your help.
