Can someone tell me why do I have arp table entry outside interface network?
Server has 2 interfaces, both on the same network:
default via 10.10.32.2 dev eth0 proto static metric 1024
10.10.32.0/22 dev eth0 proto kernel scope link src 10.10.34.146
10.10.32.0/22 dev eth1 proto kernel scope link src 10.10.33.188
Address HWtype HWaddress Flags Mask Iface
126.96.36.199 ether d4:d7:48:b5:a3:c1 C eth1
188.8.131.52 ether d4:d7:48:b5:a3:c1 C eth0
And then, when I ping 184.108.40.206 (from eth0) I get icmp reply but arp table does not change.
But when I ping -I eth1 220.127.116.11 I get icmp reply and there is a new entry in arp table:
18.104.22.168 ether d4:d7:48:b5:a3:c1 C eth1
But, when I add 'ip route add default via 22.214.171.124 dev eth1' to the routing table and ping 126.96.36.199 from eth1 there is no new arp table entry for 188.8.131.52.
Why is that?
NOTE: Both interfaces are connected to Cisco switch with 'ip local-proxy-arp' on the SVI with ip 184.108.40.206/22 which is default gw, and both are in Private VLAN.
