Posting in netdev, since bonding-devel looks like isnt active anymore.
Has anyone got arp_ip_target to work on mode=2 i.e. balance-xor
layer3+4 xmit mode?
Here is my bonding_opts
mode=2 xmit_hash_policy=layer3+4 arp_ip_target=10.0.0.62 arp_interval=30000
I see from tcpdump that arp requests to 10.0.0.62 are sent to both
links, and both arp replies are got back too. However, bond0 shows
"NO-CARRIER".
Few things specific to my environment if these affect.
1. NOARP flag is set for bond0 - should it affect? I removed that
NOARP flag, and still the same behavior.
2. the arp_ip_target is also the gateway ip address of the host. There
is a default route to 10.0.0.62 on the hosts routing table.
3. Two switches reply to the same arp_tpa 10.0.0.62 arp request with different
mac-addresses. Essentially all I want from arp_ip_target is the receipt
of an ARP reply such that the bonding keeps the link on its transmit
decision, not necessary populate the arp table on the host.
Thanks
Nitin
