Solved my own problem - see CSCdu43762 on the CCO.  Shows up with the 7200
and an NSE-1 and (evidently though they are not listed) the 1760, 2621,
2621XM, 2611 and 1720.  Solution is to turn off PXF (rate limiting of ICMP
unreachables) using:  no ip icmp rate unreach
 
Lesson learned?  Read everything... :)

        Why does traceroute seem to have problems with the second check of a final
hop?
         
        RouterA-----RouterB
         
        When trace from routerA loopback to routerB loopback, first one comes back
fine, second is a * and third is fine.  Seems wierd - 500 pings all go swell.
        Then to top it off... RouterA trace to RouterA loopback0, first one comes
back fine, second is a * and third is fine.  500 pings all go swell.
         
        I've tried over ethernet, fast ethernet, serial (HDSL and frame relay).
         
        Same behavior on my 2600's and 1700's.  All running 12.2.13T.  I wasn't
able to find anything on the CCO this evening.
         
        Thoughts?
