Hi,
Problem statement:
If a ovs-bond is configured with LACP active-active mode (SLB-balancing) and
the one of the links go down and come back up again, we observe a packet drop
for few seconds.
Environment:
Openvswitch version - ovs-vsctl (Open vSwitch) 2.9.3
DB Schema 7.15.1
DPDK version - dpdk-17.11.4
Physical nics: Intel Corporation 82599ES 10-Gigabit SFI/SFP+ Network Connection
Bond mode - LACP active-active, SLB balanced.
Steps to reproduce:
1. If one of the links go down (make it down from the ToR switch) - the
other takes over and traffic flows smooth as expected.
2. When this link becomes active again, then the VM connected to this bond
interface observes packets(UDP) drop for few seconds.
Expected behavior:
The traffic should flow without any drop, even after the interface comes up.
BR,
Satish Inakoti
