[c-nsp] SLA tracking, what do you ping?

[Jay Nakamura]

When you use IP SLA to track if an upstream is working on a ISP
connection (From customer point of view, and you are not the ISP that
knows what will be safe to ping), what do you usually configure to
ping?  I have found that one hop up from the CPE is not necessary
reliable on DSL/Cable.  I was wondering if anyone can share their
experience on what works well and what to look out for.

Thanks,
