We are nearing 255 virtual interfaces on the external side of our LVS
system. Can somebody tell me if this is going to be a hard limit or if we
can go beyond 255 on one network card?
No problem (proof of concept below):
# ip addr show dev lo | grep 'inet ' | wc -l
1
# for ((i = 1; i < 255; i++)); do for ((j = 1; j < 4; j++)); do ip addr add
127.0.$j.$i/32 dev lo brd + label lo:$i-$j 1>/dev/null 2>&1; done; done
# ip addr show dev lo | grep 'inet ' | wc -l
763
# for ((i = 1; i < 255; i++)); do for ((j = 1; j < 4; j++)); do ip addr del
127.0.$j.$i/32 dev lo brd + label lo:$i-$j 1>/dev/null 2>&1; done; done
# ip addr show dev lo | grep 'inet ' | wc -l
1
