單網路卡的基於IP別名的IPAT測試

前面測試的基於IP別名的IPAT接管中，邏輯網路中每個機器有2個網路卡，這次測試是每個機器只要1個網路卡

-bash-3.00# ifconfig -a
en0: flags=4e080863,80
        inet 12.0.0.61 netmask 0xffffff00 broadcast 12.0.0.255
en1: flags=4e080863,80
        inet 10.10.1.61 netmask 0xffffff00 broadcast 10.10.1.255
        inet 10.10.3.201 netmask 0xffffff00 broadcast 10.10.3.255
        inet 10.10.3.101 netmask 0xffffff00 broadcast 10.10.3.255
lo0: flags=e08084b
        inet 127.0.0.1 netmask 0xff000000 broadcast 127.255.255.255
        inet6 ::1/0
         tcp_sendspace 131072 tcp_recvspace 131072 rfc1323 1
-bash-3.00# rsh P61B ifconfig -a
en0: flags=4e080863,80
        inet 12.0.0.62 netmask 0xffffff00 broadcast 12.0.0.255
en1: flags=4e080863,80
        inet 10.10.1.62 netmask 0xffffff00 broadcast 10.10.1.255
        inet 10.10.3.202 netmask 0xffffff00 broadcast 10.10.3.255
        inet 10.10.3.102 netmask 0xffffff00 broadcast 10.10.3.255
lo0: flags=e08084b
        inet 127.0.0.1 netmask 0xff000000 broadcast 127.255.255.255
        inet6 ::1/0
         tcp_sendspace 131072 tcp_recvspace 131072 rfc1323 1

en1上的邏輯網路只配置了1個網路卡，基於IP別名的IPAT

拔掉P61B的en1上的網線

-bash-3.00# ifconfig -a
en0: flags=4e080863,80
        inet 12.0.0.61 netmask 0xffffff00 broadcast 12.0.0.255
en1: flags=4e080863,80
        inet 10.10.1.61 netmask 0xffffff00 broadcast 10.10.1.255
        inet 10.10.3.201 netmask 0xffffff00 broadcast 10.10.3.255
        inet 10.10.3.101 netmask 0xffffff00 broadcast 10.10.3.255
        inet 10.10.3.102 netmask 0xffffff00 broadcast 10.10.3.255
lo0: flags=e08084b
        inet 127.0.0.1 netmask 0xff000000 broadcast 127.255.255.255
        inet6 ::1/0
         tcp_sendspace 131072 tcp_recvspace 131072 rfc1323 1

可以看到只需要一個網路卡就搞定，而基於IP替換的IPAT必須要2個網路卡
