Deepak,

First of all, not all MIBs that are defined get used in practice.  I
know of no ISP that is using the ping MIB to drive pings or collect
information.  It is just too inefficient to do things that way.  I
don't think any routers implement it.  I welcome any corrections.

The tier one ISPs that I know have been and probably still are using
pings are either doing ad-hoc testing or driving tests from pizza
boxes (1U rackmounts) running *ix that do statistical collection and
if applicable raise alarms by other means.  In some cases one way
measurements are made rather than use ping at all.  Traceroute is
almost always strictly ad-hoc testing or very customized information
gathering such as the CAIDA skitter program (which doesn't use a MIB).

If we end up doing an LSP-ping MIB, which too may go unused, then
someone that thinks it will be used can write it.  IMHO it can be a
separate document.
