then run rc.lvs_dr on director and real-server(attachment is the echo of runing
rc.lvs_dr on director and real-server), I found that the config of dummy0:0,
eth0:0 are changed by rc.lvs_dr.

you can find that the config are changed, so I have to reset dummy0:0.
ifconfig dummy0:0 61.131.4.187 netmask 255.255.255.192 broadcast 61.131.4.191 up
then the route table is changed again.

reset eth0:0
ifconfig eth0:0 61.131.4.187 netmask 255.255.255.192 broadcast 61.131.4.191 up
route table also changed

Testing lvs, the speed of the client connecting lvs is very slowly, and ipvsadm
shows entries in InActConn, but none in ActiveConn.
the route table is error?
