Link-local Addresses

To use link-local addressing, first set up the proper routes:

route add default dev eth0 metric 99
route add -net 169.254.0.0 netmask 255.255.0.0 dev eth0 metric 99

Then, use avahi-autoipd to discover a valid link-local IP address:

/usr/sbin/avahi-autoipd --daemonize --syslog --wait eth0

mDNS

emerge nss-mdns

/etc/nsswitch.conf:

hosts:       files mdns_minimal [NOTFOUND=return] dns mdns
