I have included Ralph. Not sure exactly which situation will cause an Information-Request storm (just other-config)? I generally would expect a server, if it exists, to respond to Information-Request even if it returns "no" config info.

But yes should be discussed with respect to Ralphs's draft.

Now, when the Information-Request message is sent to the server, don't we expect an Information-Request storm at the server akin to a Solicit storm because INF_MAX_RT is 120 secs?  If yes,   the SOL_MAX_RT is also 120 secs which is getting changed in Ralph's SOL_MAX_RT draft.  So shouldn't Ralph's document now also address the INF_MAX_RT if the document does not already do so?
