I have sent a reply off-list containing routes and dump from babel. Unfortunately in my tiny network a 3 digit number of routes is actually installed.You're probably just seeing fallback routes. (We'd need to see your dump to be sure.)Babel keeps a redundant routing table -- it keeps routes to every destination through every single neighbour. This way, it can switch to a different route immediately when it detects that its current next-hop is down. If you have 10 neighbours and there are 60 routes in the network, you'll see 600 routes in your routing table. Don't worry, though -- a fallback route is just a 60-byte data structure, so 600 routes take less than 40kB of memory. (Fallback routes are not visible to the kernel, and are not announced over the network.) You can distinguish between redundant routes and the routes actually used by the "installed" flag -- a route that is marked as "installed" is currently used for traffic, a route that is marked as "feasible" is a fallback route that can be used straight away if necessary, a route that is not marked is an "unfeasible" route, one that cannot be used without doing a quick packet exchange to make sure that it is loop-free. My advice would be: - don't panic, in large, friendly letters; - only start worrying if babeld starts having a large RSS or uses more than a fraction of CPU; - use BabelWeb in order to better understand better what's going on in your network: https://github.com/Vivena/babelweb2 Please don't hesitate to send me a route dump (through the list or, if you're concerned about your users' privacy, by private mail), I'd be curious to see what's going on. Thanks for the input,
