Can you specify exact commands you are issuing to add/remove routes? (or "route monitor" output if you are doing this from some dynamic routing software) The following order works for me (8.2-STABLE): 16:44 [0] bibi# route add -net 54.10.208.162/30 10.11.0.1 add net 54.10.208.162: gateway 10.11.0.1 16:45 [0] bibi# route add -net 54.10.223.236/20 10.11.0.1 add net 54.10.223.236: gateway 10.11.0.1 16:46 [0] bibi# route add -net 54.10.208.130/30 10.11.0.1 add net 54.10.208.130: gateway 10.11.0.1 16:46 [0] bibi# netstat -rn -finet | grep 54 54.10.208.0/20 10.11.0.1 UGS 0 0 em0 54.10.208.128/30 10.11.0.1 UGS 0 0 em0 54.10.208.160/30 10.11.0.1 UGS 0 0 em0 16:46 [0] bibi# route delete 54.10.208.0/20 delete net 54.10.208.0 16:48 [0] bibi# route delete 54.10.208.128/30 delete net 54.10.208.128 16:49 [0] bibi# route delete 54.10.208.160/30 delete net 54.10.208.160 16:49 [0] bibi# netstat -rn -finet | grep 54 16:49 [0] bibi# > struct radix_node * rn_delete (........) > { > ... > /* > * Delete our route from mask lists. > */ > if (netmask != NULL) { > if ((x = rn_addmask(netmask, TRUE, head_off)) == NULL) > return (NULL); > netmask = x->rn_key; > while (tt->rn_mask != netmask) > if ((tt = tt->rn_dupedkey) == NULL) > return (NULL); // rn_delete return here!!! > } > ... > } > > but, if I delete as the following order, all routers was deleted > successfully: > > 0x360AD0A2/30 > 0x360AD082/30 > 0x360ADFEC/20 > > > so, is it a bug of RADIX? > > /jack > > > > > -- > View this message in context: http://freebsd.1045724.n5.nabble.com/Is-it-a-bug-of-RADIX-tp4406356p4406356.html > Sent from the freebsd-net mailing list archive at Nabble.com. > _______________________________________________ > freebsd-net@freebsd.org mailing list > http://lists.freebsd.org/mailman/listinfo/freebsd-net > To unsubscribe, send any mail to "freebsd-net-unsubscribe@freebsd.org"
