Is there a special setup require for connection mirroring to work with route domains

I have a route domain 999 configured and the VIP's are configured for connection mirroring. The HA vlan is not within the route-domain only the default route-domain 0. I can see the FastL4 connections are not being mirrored and break during a 1 sec failover. any ideas?

 

do i have to create a route domain specific HA vlan and add it to the route-domain 999?

 

I do have AFM configured and I am allowing sys default tcp/udp ports between the HA self IP peers so I dont expect the AFM portion to be block the connection mirroring ports
