Actually the all means that the configuration of the arp_ignore and
arp_announce options in general is enabled. Afterwards you then specify
the options for the specific interfaces.

Logically it appears to be like that but the 1 is not exactly an on/off
switch here. 1 means that the interface should only answer ARP requests
for IP addresses bound to that interface.
