Hello, reading the 'missing RTMGRP_***_ROUTE notifications on ifdown' thread from february this year, I see this seems to be accepted as a misfeature. http://marc.theaimsgroup.com/?t=107703402000002&r=1&w=2 While IPv6 does this as expected, IPv4 still doesn't. As I'm not familiar with the kernel code, I'd be more than happy if somebody with more clue could take a look at this. I'd even be happy if John's ideas and Henrik's notes could be confirmed and I'll try to come up with an updated patch. The missing RTM_DELROUTE messages lead to inconsitencies in zebra/quagga's RIB. While fixing zebra is an option, it is only a workaround and might get quite ugly.
