Hi.
Not sure wheter this is actually an issue or not:
When using ifconfig, respectively the old schema via /e/n/interfaces
to set up secondary IP addresses like this:
iface eth0:1 inet static
address 84.16.242.145
netmask 255.255.255.0
it will also automatically calculate the broadcast address:
e.g.
eth0:1 Link encap:Ethernet HWaddr 82:a7:3a:36:38:27
inet addr:84.16.242.145 Bcast:84.16.242.255 Mask:255.255.255.0
UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1
It seems that with iproute/ip this no longer happens for such secondary
addresses,
i.e. when doing:
ip addr add 1.2.3.4/27 dev eth0 label eth0:0
I'd get:
inet 1.2.3.4/27 brd 0.0.0.0 scope global secondary eth0:0
valid_lft forever preferred_lft forever
I really have to set it manually as in
ip addr add 1.2.3.4/27 broadcast 1.2.3.4 dev eth0 label eth0:0
to get
inet 1.2.3.4/27 brd 1.2.3.223 scope global secondary eth0:0
valid_lft forever preferred_lft forever
But as said... I'm not sure whether this is intended at all or a feature.
Cheers,
Chris.
