-Subject: [PATCH 1/2] Babel: Add option to randomize router ID
-
-When a Babel node restarts, it loses its sequence number, which can cause
-its routes to be rejected by peers until the state is cleared out by other
-nodes in the network (which can take on the order of minutes).
-
-There are two ways to fix this: Having stable storage to keep the sequence
-number across restarts, or picking a different router ID each time.
-
-This implements the latter, by introducing a new option that will cause
-BIRD to randomize a high 32 bits of router ID every time it starts up.
-This avoids the problem at the cost of not having stable router IDs in
-the network.
-
-Thanks to Toke Hoiland-Jorgensen for the patch.
