Currently, Multi-EFA configured cluster nodes are disabling Source Destination Check on all the EFA ENI to enable proper routing. However, this approach is sub-optimal, and forces the instance to act as a router across the multiple EFA ENIs.
Better approach would be to update the instance routing tables and routing rules to allow proper routing across all the EFA ENIs.
