I created an operation on the source router specifying the source and destination addresses of the multilink interfaces. However when I go into the destination router and do a "sh ip sla conf" to view what config SW has added, I see ethernet addresses in the "Target address/Source address". (I created a "VoIP UDP jitter" operation in SW for this). All of the other parameters for the operation appear to be correct as I configured them. Why is SW changing the addresses? Has anyone else noticed this, or am I doing something wrong?
