Hi Peter, I'm getting: # route -T75 default ::1 -blackhole route: botched keyword: default usage: route [-dnqtv] [-T tableid] command [[modifiers] args] commands: add, change, delete, exec, flush, get, monitor, show
or: # route -T75 add default ::1 -blackhole route: ::1: bad address Am I missing something in your message? (Is this btw a general recommendation or a proposed solution?)
