Hi, Just wondering if the following command should work: # ip route add 192.168.27.27/24 dev eth0 scope link src 192.168.27.27 RTNETLINK answers: Invalid argument However, this command works: # ip route add 192.168.27.0/24 dev eth0 scope link src 192.168.27.27 192.168.27.0/24 and 192.168.27.27/24 describe the same subnet? Regards, Marcus.
It is the kernel complaining, not ip command. The kernel will not accept 192.168.27.27/24 as route since it is a full network address, not an network prefix.
