Return to control.h CVS log

Up to [local] / src / usr.sbin / ripd

Welcome ripd
started by Michele Marchetto some time ago by using the imsg/three process framework
of ospfd. He implemented most of the daemon with a little help and guidance from
Claudio and I.

Currently the daemon is more or less complete, with the exception of key lifetime
and rollover.

Not yet connected to the builds.
