linux - Why ARP requests a non-local address? -


i have linux virtual server 2 nics.

eth0 <ip1> eth1 <ip2>

arp_filter turned on , rp_filter set 2(loose mode).
policy-routing configured following: 

table t1 default via <gw> dev eth0 src <ip1> 127.0.0.0/8 dev lo <lan> dev eth0 src <ip1>  table t2 default via <gw> dev eth1 src <ip2> 127.0.0.0/8 dev lo <lan> dev eth1 src <ip2>  ip rule add <ip1> table t1 ip rule add <ip2> table t2

after that, can ping both binding floatingips of <ip1> , <ip2> outside. ping -i eth1 <some_domain> dosen't work. tcpdump shows when ping eth1 outside, linux directly asks mac of outside address, incorrect because not in same lan.

here tcpdump data: 

root@rm-2:~# tcpdump -i eth1 arp tcpdump: verbose output suppressed, use -v or -vv full protocol     decode listening on eth1, link-type en10mb (ethernet), capture size 65535     bytes 17:53:08.696191 arp, request who-has 172.30.250.119 tell 172.30.248.2, length 46 17:53:08.728482 arp, request who-has 172.30.251.144 tell 172.30.251.138, length 46 17:53:09.447252 arp, request who-has 61.135.169.125 tell 172.30.251.43, length 28 17:53:09.551514 arp, request who-has 172.30.250.127 tell 172.30.248.2, length 46 17:53:09.698076 arp, request who-has 172.30.250.119 tell 172.30.248.2, length 46 17:53:09.859046 arp, request who-has 172.30.248.246 tell 172.30.248.245, length 46 17:53:10.446009 arp, request who-has 61.135.169.125 tell 172.30.251.43, length 28 17:53:10.477104 arp, request who-has 172.30.250.128 tell 172.30.248.2, length 46

as can see, 61.135.169.125 foreign address, bug or something?

edit
output of route: // 172.30.248.1 gw 

destination     gateway         genmask         flags metric ref    use      iface   default         172.30.248.1    0.0.0.0         ug    0      0        0      eth0
