I forgot to mention that the different defaults for physical interfaces vs. VLAN interfaces is due to olsrd changing the default in /proc/sys/net/..., thus interfaces created by the kernel and not touched by olsrd still got the original default from kernel (send_redirects being switched on) while virtual interfaces being created later on, eg. by network restart and such where VLANs on top of a physical ethernet interface are being created, those will have the new default previously set by olsrd (ie. send_redirects will be switched off). Due to this, the value of send_redirects after a network restart for interfaces *not* used by olsrd suddenly differs depending on whether they are 'physical' (e.g. eth0) interfaces or virtual interfaces (eth0.1)... At least allowing to explicitely configure send_redirects in netifd seemed to be the easiest way to improve the situation significantly without hurting anyone. _______________________________________________ openwrt-devel mailing list openwrt-devel@lists.openwrt.org https://lists.openwrt.org/cgi-bin/mailman/listinfo/openwrt-devel
