我想用一个linux-boxtesting一个networking，它应该得到100个不同的IP地址，每个IP地址都有一个自己的MAC，当与其他设备通信时，它应该被用作源MAC地址。
我已经写了这个：
#!/bin/bash for i in `seq 0 10 `; do hex=`perl -e "printf ('%02X', $i)"` echo tap$i / $hex ip link add link eth0 address 00:00:13:37:00:$hex eth0-$i type macvlan done sleep 2 for i in `seq 0 10 `; do echo eth0-$i ip while ! ifconfig eth0-$i &>/dev/null; do sleep 1 done ii=`expr $i + 100` ip addr add 10.254.251.$ii/24 dev eth0-$i ifconfig eth0-$i up done 然后我得到我自己的IP和自己的MAC地址的设备。
但是，当从外面的任何一个ARP地址为我的一个IP地址的Linux主机通过eth0与我所有的虚拟地址应答多次，其他设备然后插入最后一个在其ARP表。

有没有人有我的想法如何设置？ iIs macvlan是错误的吗？
使用Linux brige我可以做类似的设置，但是主机回复所有IP与出口接口的物理MAC。
看看arp_filter和arp_ignore 。
/proc/sys/net/ipv4/conf/*/arp_filter ， /proc/sys/net/ipv4/conf/*/arp_ignore
