-Subject: [PATCH] babel: Set onlink flag for IPv4 routes with unreachable next
- hop
-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-
-If the next hop of a route is not a reachable address, the route should be
-installed as onlink. This enables a configuration common in mesh networks
-where the mesh interface is assigned a /32 and babel handles the routing by
-installing onlink routes.
