Cisco ASA Global Policy Equal Cost Multi Path over different interfaces

Hello,

We have an ASA we've configured with global policy.  It's attached to the core switches with two /30 interfaces with OSPF.  These interfaces learn equal cost routes to subnets on the core.

We seem to be having a symmetry and state issue i.e. Traffic needs to go in and out of the same interface or it doesn't pass.  However, the log doesn't show drops, a trace passes and a packet capture shows the traffic leaving (but it never really leaves).

Is the approach we have supported?  Is there a way to turn off the interface reference in the stateful tuple?

ASA-5585X on 9.3.

Cheers,

Mike

Hi,

I think this is not supported at the moment but will be supported in the future ASA releases.

Thanks and Regards,
