I'm wondering what is the purpose of a routing table entry named 'link-local'.
root# route
Kernel IP routing table
Destination Gateway Genmask Flags Metric Ref Use Iface
192.168.178.0 * 255.255.255.0 U 1 0 0 eth0
link-local * 255.255.0.0 U 1000 0 0 eth0
default fritz.box 0.0.0.0 UG 0 0 0 eth0
when I print the routing table with -n I get:
root# route -n
Kernel IP routing table
Destination Gateway Genmask Flags Metric Ref Use Iface
192.168.178.0 0.0.0.0 255.255.255.0 U 1 0 0 eth0
169.254.0.0 0.0.0.0 255.255.0.0 U 1000 0 0 eth0
0.0.0.0 192.168.178.1 0.0.0.0 UG 0 0 0 eth0
So it seems that link-local refers to 169.254.0.0. What's the purpose of it? I have never configured such a route, and I cannot find an entry for that in my fritz.box router.
