When the validity of prefix/address/router is checked, the own router advertisements and static address assignments are not considered. The attached patch does not fix the problem, but works for me as a workarou= nd, because I use a unique local address for the FreeBSD router. That should al= so work for the original bug reporter. The patch does not prevent the change of address state to "detached", but keeps the route working and allows a static address with same prefix. --=20 You are receiving this mail because: You are the assignee for the bug.=
