arp flux when multiple nics are in the same segment #237
Description
We have multiple NICS on the same segment that are going to be bonded. eDeploy runs dhclient on all interfaces and receives different ip addresses for each NIC. This works as expected.
After a while dhclient tries to refresh its ipaddresses and contacts the dhcp server with its lease. The dhcp server tells the dhclients that they can still use their ip addresses. Dhclient then verifies that noone on the same network segment has this particular ip adress configured using an arp request. It gets a response, and dhclient removes the ipaddress from the interface.
The problem is that it gets a response from itself. eth0 receives an arp response from eth1.
I suggest setting arp_filter to 1 during deployment.
