Hello, I submit two patched. 0001-PATCH-FLX-Add-command-line-option-for-specifying-the.patch The first one is to add the -P <pidfile> argument on the command line. On some distributions, the pidfile is managed into the start script and not into the configuration file. 0003-FEAT-Add-protocol-volatile.patch The second patch is new protocol. I named it "protocol volatile". This permit to add routes into bird via the control socket. These route are volatile: when bird restart, they are lost. This is useful for servers using transparent redirect and transparent binding like "squid" or "haproxy". This two softs can receive trafic for an ip not present on the system. This new feature "protocol volatile" permit to do high avalaibility infrastructure with announcing these routes only if the service is avalaible. This permit also to do load-balacing: if many computers annouce the same route, the router can be use ecmp algorithm for the repartion. Thierry FOURNIER
