   5
   6 Accepted upstream and will be included in 3.9.8.

   9 A subnet is missing in the DVMRP report sent to it's neighbor after
  10 the initial probe occurs.  The issue was with the traversal of a double
  11 linked list from end to start. Once the traversing pointer reaches
  12 the start of routing table for loop (condition) it would break and
  13 always drop the first subnet.
