[snip] > redistribute local ip 192.160.7.0/24 eq 24 metric 128 "redistribute local" is for redistributing local addresses, not external routes. For redistributing routes, you say something like redistribute ip 192.160.7.0.24 eq 24 metric 128 Make sure the routes are installed in the kernel with a proper protocol number -- "ip route show" will tell you.

Hysteresis? If the two routes have roughly similar metrics, Babel avoids switching for what will be little gain. Try doing killall -USR1 babeld and check if Babel is taking sub-optimal decisions given the data that it has. FYI, Babel will switch routes if either the metrics differ by more than 192, or the metrics differ by more than 64 and the source ids are the same. (For an external route, the source id identifies the border router this route was injected by.) > for wired failures a retraction should be issued more rapidly than > that, and the link should change to the other route in x amount of > time. Babel's default configuration assumes that wired links are stable, so the wired hello interval is set to a very large value. It's tweakable, so feel free to experiment (either -H on the command line, or hello-interval in the config file). I'm seriously thinking of changing this default, as it is apparently a FAQ. > Is there some relation to rxcost to time? I'm not sure I understand your question. Maybe you'll find Appendix A of the Babel draft enlightening?
