Subject: [ripd] Fix logic to send updates on all connected addresses.
2006-04-28 Andrew J. Schorr <ajschorr@alumni.princeton.edu>
* ripd.c: (rip_update_process) Try to fix the logic for sending
an updated on each connected network. The new code will
attempt to send the update on each connected network, whereas
the previous code seemed to be attempting to avoid sending
more than one RIPv1 update on a given interface, but was coded
incorrectly. The actual effect of the old code was to send
an update only on the first connected address in the cases
where the interface is not multicast, or RIPv2 is not being used.
