From 687f41680d51585e9a5a135e39efee330588bea7 Mon Sep 17 00:00:00 2001 From: Matt Weber Date: Fri, 11 Sep 2015 12:49:30 -0500 Subject: [PATCH 1/1] DVMRP report missing subnet Accepted upstream and will be included in 3.9.8. https://github.com/troglobit/mrouted/commit/512af5ffe0f48ffa2ba3b45898c66c2a561a5c2d A subnet is missing in the DVMRP report sent to it's neighbor after the initial probe occurs. The issue was with the traversal of a double linked list from end to start. Once the traversing pointer reaches the start of routing table for loop (condition) it would break and always drop the first subnet.
