Right - I can't recall whether it was on c-nsp or NANOG, but I think the
issue was that someone was saying that using CSR1000v as an IP SLA probe
had some internal forwarding latency issues, compared to a classic
software-based router like a 2800, 3800 or 7200.

I can't speak to how true this is. Our CSR1000v's are RR-only, and do
not forward any traffic. Handling of exception traffic has been great
with no issues so far, which would imply - at least for me, anyway -
that it should be fine as an IP SLA probe since the box terminates that
type of traffic, it does not transit it.

Not sure whether the issue could be related to hardware, choice of
hypervisor, e.t.c.
