| 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. |
